Preheat the air fryer or oven to 425F and prepare a baking sheet with parchment or the air fryer tray.
Add the cauliflower, green pepper, red pepper, red onion, olive oil and fajita seasoning to the tray and toss until completely mixed.
Air fry for 8 to 9 minutes, tossing halfway through, until the cauliflower is brown and tender. Alternatively, roast in the oven for 20 to 25 minutes.
At this time, make your rice according to the package directions if you're having it.
Assemble the burritos with the roasted vegetables, rice and queso. Wrap and enjoy.
Optionally, toast the burrito in a skillet. Place seam-side down and cook over medium heat until browned on each side.
Enjoy immediately. If meal prepping, store all of the ingredients separately until eating for best results.
Notes
In addition to the cauliflower and bell pepper filling, you can customize your burrito however you like! Add beans or tofu for extra protein, rice or sweet potato, avocado, salsa, cashew cream... The sky is the limit!
If you're using rice, try this recipe with cilantro-lime rice for a brighter flavor, quinoa for extra protein, or cauliflower rice to make it a double feature.
Most of the recipe is gluten-free. You can swap flour tortillas for gluten-free options like corn or oat tortillas. Alternatively, enjoy this filling in lettuce or collard green wraps, or make it into a burrito bowl.
Toast your burritos in a skillet for a crispy exterior, cook in a grill press or bake in the air fryer. Lots of ways to cook them using the equipment you have. You can even microwave these cauliflower burritos, although they won't be crispy if you do that.
