  • 1 ½ cup corn salsa
  • 1 cup Pico de Gallo
  • 1 cup guacamole
  • 4 tablespoons vegan sour cream
  • 6 small flour tortillas
  • 2 tablespoons oil

For mushroom fajitas:

  • 6 large portobello mushrooms
  • 1 red bell pepper
  • 1 yellow bell pepper
  • 1 green bell pepper
  • 1 red onion
  • ½ lime, juiced
  • ½ teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon oregano
  • salt and pepper to taste

For the mushroom marinade:

  • 3 tablespoons soy sauce
  • 1 tablespoon water
  • 1 tablespoon olive oil
  • ½ lime, juiced
  • 2 cloves garlic, minced
  • ¼ teaspoon freshly ground black pepper


  • Slice the mushroom cups into thick ½-inch strips. 
  • Prepare a marinade for the mushrooms: in a bowl mix soy sauce, water, olive oil, lime juice, garlic, and pepper. Place mushrooms into the marinade and stir until evenly coated, cover a bowl with a lid and put into the fridge for 30 mins.
  • In a meantime, slice the bell peppers into thick long strips, also slice the onion lengthwise into large chunks. Put bell peppers and onions into a big bowl and cover with spices: chili, cumin, paprika, oregano, salt, and pepper. Drizzle with lime juice and stir.
  • Heat olive oil in a large skillet over medium heat. Add the seasoned vegetables and cook for about 6 minutes.
  • Remove the mushrooms from the marinade and add to the skillet. Stir everything and cook for another 6-7 minutes.
  • Heat a ½ tablespoon of oil in a skillet and toast tortillas until browned and to desired crispness on both sides, then make a taco shell and arrange all the fillings. Serve with vegan sour cream and enjoy.


  • Store leftovers in separate airtight containers and keep in the fridge for up to 3 days.
  • It's best to use fresh tortillas when you're ready to eat your tacos again. That way you can be sure to have a crispy shell!
