Bell Pepper Caramelized Onions & Mushroom Sandwich

Updated: Jul 28, 2018

Sandwich #2 of 3 sandwiches featured in my 3 Easy Vegan Sandwich Ideas video.

You will not believe how incredibly indulgent this sandwich tastes, despite being super healthy and 100% plant-based! All of the flavors were simply made for each other!

First you've got the creamy hummus and the nutty salty flavors of the pesto. Then you have the fresh peppery arugula combined with the sweetness from the charred red bell pepper and the luscious caramelized onions and mushrooms! Now take all that, put it in a lavash wrap and grill to perfection! I mean, how could that not be amazing?!

And the way the hummus melts into the pesto to create this creamy almost cheese-like texture. Ooh yeah... I'm getting hungry!

• 1/2 tbsp. extra virgin olive oil

• 1/4 yellow onion

• 1/2 cup cremini mushrooms

• 1/2 tbsp. tamari or soy sauce

• 1/2 red bell pepper (any bell pepper works too!)

• whole wheat lavash wrap (substitute pita bread or whole wheat flour tortillas)

• 2 tbsp. hummus

• 2 tbsp. vegan pesto

• 1/2 cup arugula


  1. Prep your veggies. Thinly slice the onions & mushrooms and quarter the red bell pepper.

  2. Preheat and oil your pan with the extra virgin olive oil.

  3. Add in your onions and sauté for 2 to 3 minutes on medium heat. Throw in your mushrooms and the tamari or soy sauce, and cook for another 5 to 6 minutes, stirring occasionally. Your onions and mushrooms should be soft and browned up nicely! If they're still a bit pale or hard, don't be afraid to cook it for longer.

  4. Now transfer your caramelized onions and mushrooms to another plate while you cook up the red bell peppers in the same pan. The pan should still be hot so no preheating necessary at this point. Just grill your bell peppers for 2 to 3 minutes just till they're charred on either side. Use your spatula to press it down in order to help it along.

  5. Time to assemble! Cut your lavash wrap in half to make 2 sandwiches. Spread the hummus and pesto on the wrap and, on one side of the wrap, layer in the cooked veggies along with the fresh arugula. Fold the lavash wrap in half sandwiching all the ingredients together.

  6. You're not done yet! Using the same pan you used to cook the veggies (because why not, less clean up!), grill your sandwich for 2 to 3 minutes on either side. The contents should be nice and gooey and the lavash wrap should be beautifully browned with slightly crisped edges. Now you're ready to dig in!
