These cauliflower tacos with fajita veggies are the kind you make when you want something easy that still feels like a win at the table.

Roasted Cauliflower Tacos
These cauliflower tacos with fajita veggies are crunchy, well-seasoned, and baked in the oven, so they're easy to make. The taco seasoning gives them that classic flavor, and at my house, we finish them with my cilantro sauce… which we love on everything.
Ingredients
The veggies in these tacos are cauliflower florets, onion, and bell pepper. To coat them with flavor, you’ll need olive oil and taco seasoning. Finally, i use corn tortillas to serve these tacos.
Using Frozen Cauliflower
Frozen cauliflower releases steam as it roasts, which can make the florets and nearby veggies softer instead of crispier. This is not a big deal since everything still tastes delicious. If you want a crisp texture to all the veggies, thaw and drain any liquid first before adding the cauliflower to the sheet pan.
How to Make Cauliflower Tacos with Fajita Veggies
