Step 1

Preheat oven to 400°F.

Step 2

On a large rimmed sheet pan, toss the bell peppers and onions with 1 tablespoon olive oil and 1 tablespoon fajita seasoning until everything is coated (I like to use my hands for this).

Step 3

Mix the remaining oil and seasoning in a medium sized bowl. Add shrimp and stir until shrimp is well-coated. Let marinate in refrigerator while peppers and onions roast.

Step 4

Place pan in preheated oven and bake for 20 minutes.

Step 5

Add shrimp, stir, and bake for 8-10 minutes more or until shrimp is cooked through and looks pink and opaque. Meanwhile, warm tortillas if desired, and prepare toppings.

Step 6

Serve immediately on warm tortillas with your favorite toppings.
