Portabella Burgers with Chimichurri Guacamole
I desperately need help!  I NEED a new pillow and I cannot seem to find one that is perfect for my weary head.  My pillow literally gives me a pain in the neck.  A BIG PAIN IN THE NECK!  Nothing will ruin your day more than when you wake to find that you cannot turn your head to the left.   Because when you do turn your head to the left, your neck screams in pain!  It makes me a very grumpy woman.
 I’m not just grumpy for the day, I’m grumpy for the rest of the week!  That’s how long it takes for this horrid pain to go away!  Trust me,  you’d be grumpy too if you were walking around like Quasimodo.   I actually have to turn my entire torso to see anything to my left.    It’s a blessing for our kids.  As long as they stay to my left, they can get away with anything!
I just don’t understand how it can be so difficult to find the perfect pillow.  I’ve tried several different styles of firmness, and filling AND from several different stores, all  to no avail.  I finally broke down and spent an obscene amount of money on a specialty pillow only to find instead of cradling my tender nape, it rudely props my head up and consistently cricks my neck.  I hate it.  I give it dirty looks every night.  Then I punch it down with all my might and say mean things to it.   I’d give my husband jealous stares, but he’s to my left and I can’t see him.
Portabella Burger with Chimichurri Guacamole
It’s been a difficult week in the kitchen.  It’s kinda hard cooking when your left shoulder is raised up to your earlobe in the vaguest attempt to rest your neck.   I had big plans of making mac and cheese, but I couldn’t lift the stock pot.  I know, I sound  pathetic to myself.  So we ate breakfast for dinner…a lot.  Don’t judge me.  I was in survival mode.
Finally by the weekend I was feeling good.  Granted, it could’ve been the wine and the Motrin, but who cares!!!  I was back in action!  I was ready to throw myself into the kitchen!  I joyfully made donuts and whoopie pies (yummy future posts) turning to my left as often as possible!   I was all set to make a huge stock pot full of pasta (because I could) when an intense craving for chimichurri hit.  I’ve never actually had chimichurri mind you. But I knew it had cilantro, which lead me to guacamole which somehow got me thinking about portabella mushroom burgers!   And BOOM, just like that this meal was born.
Chimichurri Guacamole
 Portabella mushrooms can be incredibly meaty and delicious.   They taste exquisite in any dish, but on the grill they are simply divine.  I  added some Pepper Jack cheese to our burgers because I can’t seem to eat food without the teeniest bit of heat.   It was an outstanding combination of flavors and textures!  You ever have those meals where you groan with every bite because they are THAT GOOD?  These portabella mushrooms  were that kind of meal.  Insanely good.  Why can’t my pillow be that good?

  1. This burger looks incredible! I love everything in there…chimichurri happens to be one of my favorite things and I love the idea of mixing it into guacamole. Delicious!

    • Thank you Marcie! I am smitten with this burger!

  2. I have never had a Portabella burger…I’m scared of them. LOL But this recipe makes me want to try one.
    Visiting from Jam Hands.

    • Nothing to fear, I promise!!! They really don’t not have the mushroom flavor you are expecting! They are wonderful!

  3. Sounds like you need to be adjusted ,Tanya! Being married to a chiropractor and almost becoming one myself, I should know :) You can also sleep on your back with a rolled up towel under your neck, but that takes some getting used to…

    I love mushrooms, but it’s the one food my hubby doesn’t like, so I could never make such a mushroom-centered meal. Looks delicious to me though!

    • I seriously need your help then Loretta!!! My poor neck! My husband wasn’t sure about this one, but surprisingly, he loved it!

  4. Cathy

    Lol! I wished I could “like” so many parts of this post…too funny. I also have a crummy pillow and I’ve resorted to using a decorative lumbar pillow in addition to my regular one. It works! These portabellas look insanely good, Tanya!

    • Ooh, thanks for the tip Cathy!!! I will have a happy neck one of these days!

  5. Yikes! I hope your neck starts feeling better. Nothing worse than a neck ache that is so bad you can’t turn your head. But, I love the chimichurri guacamole idea :)

  6. Your opening photo says it all, Tanya. That is one tasty looking burger — and healthy, too. It’s not often you can use burger and healthy in the same sentence. :)

    • You are right John, burgers are not synonymous with healthy! Too bad huh?

  7. Awesome recipe. I love portabella burgers! The idea of a chimichurri guacamole in top is genius! Can’t wait to try this, definitely pinning. :)

    • Thank you Krista! The guacamole is soooo good! Good enough to eat on its own!

  8. You crack me up Tanya! I hear you about the pillow thing…the search for a perfect pillow is very time consuming. Most don’t understand.
    This is a great recipe! My hubs would love this. (=

    • Thank you for understanding Gloria! And my burger loving husband absolutely loved this vegetarian version!

  9. I have all these herbs on my porch! Score!!
    So sorry your pillow is a pain in the neck– nothing is worse than a crummy night’s sleep. Hope you find a new AWESOME pillow.

    • How lucky to have cilantro and parsley on your porch! You will love these!

  10. Mmmmmmmmmm…………I just LOVE bella burgers but with the addition of the special guac, I know it was just fantastic!

    • I thought it was fantastic, but I am certainly biased!

  11. I hope you find a good pillow soon!! It’s hard to do much in a day with a nasty kink in your neck! These burgers look/sound fantastic!!! Yum!!

  12. Neck kinks are the worst! One of the many reasons I love my Chiropractor! This is a beautiful burger I can’t wait to try it

    • I might need a chiropractor! I loved this burger!

  13. Oh my, nothing quite like avocado, mushrooms and a nice, thick burger to kiss those angries away – mouthwatering!

  14. Tanya, I love all the flavor you packed into this portabella burger especially the chimmichurri. It will be a Thursdays Treasure Feature.

    You should try a Tempurpedic pillow! I LOVE mine!

    • I have to look into that Sandee! Thank you.

  17. Ashley

    Made these tonight and they were delicious!! They will definitely be making an appearance on our table again very soon! One quick question: is the 2 Tbsp olive oil for the chimichurri and the 1/2 c for drizzling on the mushrooms? That’s how I did it tonight but just wanted to clarify. Thanks!

    • I am so happy to hear this! Those burgers are my all time favorite!
