- 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.

- Heat a ½ tablespoon of oil in a skillet and toast tortillas a little bit on both sides, then make a taco shell and arrange all the fillings. Serve with vegan sourcream and enjoy.
Tips For Success
- If you're making everything homemade, it's best to prep your corn salsa, Pico de Gallo, and guacamole ahead of time so the flavors really set in. Keep it in the fridge until you are ready to serve.
- You can use different mushrooms, or maybe a blend, if you'd like some different textures. Oyster and shiitake mushrooms also work amazing!
- If you want your tacos a little heartier, add some black beans or load up with more vegetables.
- Want soft tacos instead? Wrap them in foil and warm them in the oven at 350F for 20 minutes.
Storage
- 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!
