20-Minute Shrimp Fajitas Sheet Pan Dinner

Preheat the oven to 450 degrees F (230 degrees C). Spray a rimmed baking sheet with cooking spray.

Combine shrimp, bell peppers, red onion, olive oil, chili powder, salt, black pepper, garlic powder, onion powder, cumin, and paprika in a large bowl; toss to combine. Spread mixture on the prepared pan evenly.

Cook in the preheated oven until shrimp are bright pink and firm, about 8 minutes. Turn on the oven's broiler and cook for an additional 2 minutes.

Squeeze lime juice over mixture.

Build fajitas on tortillas with avocado slices and cilantro.
