Preheat the oven to 400°F. Line a large baking tray with parchment paper and set it aside. In a small bowl, whisk together the seasonings.

Place the peppers and onions into a large bowl and toss them with 1 tbsp of the olive oil. Then toss them with 1 1/2 tsp of the seasoning mix. Spread them out evenly on the prepared pan and put it in the oven for 12 minutes. While the veggies get a head start, place the shrimp into the bowl and toss them with the additional tbsp of olive oil and the rest of the seasoning. Stack up your tortillas and wrap them in foil.
