It was love at first bite.

They are as easy to make as chopping some veggies, marinating them, and throwing them in a skillet. This recipe is perfect for Meatless Monday, or any time you are looking for a veg-packed meal.
Ingredients for Making Vegetarian Fajita Recipe
- Oil: Avocado oil is my go-to oil for high-heat cooking.
- Lime Juice: Fresh lime juice is best. For an extra punch of flavor, zest the lime before you juice it.
- Seasonings: A blend of chili powder, garlic powder, smoked paprika cumin, salt, and pepper adds the much-loved fajitas flavor. Onion powder is another great option. In a hurry? Substitute a packet of taco or fajita seasoning.
- Vegetables: I used red onion, bell peppers, mushrooms, zucchini, and garlic, but feel free to play with this and use what you have on hand.
- Tortillas: I used white corn tortillas, but you can use yellow corn or flour tortillas if you like. A lettuce wrap is another great option.
- For Topping: Use traditional fajita fixings: avocado, guacamole, salsa, hot sauce, sour cream, and cheese are all great options.
Mix It Up!
- Add one minced chipotle chili pepper and one tablespoon of adobo sauce to the marinade for a kick of heat.
- I used corn tortillas to keep it gluten-free, but you can use whatever tortillas you prefer.
- To add sweetness, add two teaspoons coconut sugar to the marinade.
- Skip the avocado or guacamole and instead serve with Mango Avocado Salsa.
- You can add black beans, garbanzo beans, or quinoa to your tortillas for an extra kick of protein.
What Do You Serve With Vegetable Fajitas?
- Lime rice, Mexican Quinoa or Spanish Cauliflower Rice all make great sides.
- Rainbow Citrus Slaw is an unexpected option that is ridiculously good.
- Slow Cooker Black Beans make a fabulous side, and work well in the fajitas too.
