Preheat the oven to 425 F and line a large sheet pan with parchment paper.
In a small bowl, combine all the taco seasonings to make the mix. (1/2 tablespoon chili powder, 1 ½ teaspoon ground cumin, 1 teaspoon fine kosher sea salt, 1/4 teaspoon ground black pepper, 1 tablespoon smoked paprika, 1/2 teaspoon garlic powder, ¼ teaspoon onion powder, and 1/2 teaspoon dried oregano)
In a large bowl, add the 1.5 pounds raw jumbo shrimp, 2 bell peppers, and 1 large red or sweet onion. Drizzle with 2 tablespoons olive oil, 1 lime juice and sprinkle with the seasoning.
Toss well to coat. Spread the shrimp mixture over your prepared sheet pan.
Bake for 16-18 minutes, then flip and broil for a couple of minutes. Serve with 12 small corn tortillas is preferred.
Notes
You may use different colored bell peppers or stick to one color.
I like using jump shrimp, but you may use large. It is best to use raw shrimp. These can be found in the frozen section. They also come already peeled and deveined. It will save you time.
If you have any store-bought taco or fajita seasoning you like, you can use that instead. More time-saving.
