Step 1

Preheat oven to 425 degrees F. Lightly oil a baking sheet or coat with nonstick spray.

Step 2

Place bell peppers, onion and garlic in a single layer onto the prepared baking sheet. Stir in 2 tablespoons olive oil and half the chili powder mixture; gently toss to combine.

Step 3

Place into oven and bake for 10 minutes, or until the vegetables are beginning to soften.

Step 4

In a large bowl, combine shrimp and remaining 1 tablespoon olive oil and chili powder mixture.

Step 5

Working carefully, move vegetables onto one side of the baking sheet. Place shrimp onto the opposite side of the baking sheet in a single layer.

Step 6

Place into oven and bake just until shrimp are pink, firm and cooked through, an additional 6-8 minutes. Stir in cilantro and lime juice.

Step 7

Serve immediately with desired tortillas.

Step 8

In a small bowl, combine chili powder, cumin, oregano, paprika, 1 teaspoon salt and 1 teaspoon pepper.
