  • 1 cup olive oil
  • 2 tablespoons Worcestershire sauce
  • 2 garlic cloves, minced
  • 1 lime, juice
  • 4 teaspoons taco seasoning
  • 1/2 teaspoon ground cumin
  • 3 bell peppers, seeds removed and thinly sliced
  • 4 large portobello mushrooms, gills removed and thinly sliced
  • 1 small red onion, thinly sliced
  • 6 medium sized corn or flour tortillas

Optional Toppings


  • Combine olive oil, Worcestershire sauce, minced garlic, lime juice, taco seasoning, and cumin.
  • Add the sliced bell peppers, portobello mushrooms, and red onion to a large ziploc bag with the marinade. Zip to seal and shake until veggies are fully coated. Marinate at room temperature for 30-60 minutes, flipping the bag over halfway through.
  • Preheat the oven to 450° F and arrange the marinated veggies in a single layer on a baking sheet. You might want to split them between two baking sheets. Bake for 20-25 minutes, until mushrooms begin to brown.
  • Remove the veggies from the oven and preheat the broiler to high. Place the veggies back in the oven about 3 inches from the heating element for 4-5 minutes until charred to your liking.
  • Serve with warm fajitas and desired toppings.
