Last But Not Least. Save this for last. You want hot shrimp on your tacos, and they won't take long to cook.
Coating. In a bowl, measure and combine all the spices, herbs, and seasonings.
1/4 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon salt, 1/2 teaspoon lemon pepper, 1/2 teaspoon oregano, 1/2 teaspoon sugar, 1/2 teaspoon paprika
Drain. Drain the shrimp and pat dry in paper towels. This is an important step. If you don't paper towel dry, when the shrimp cook, they will end up in a pool of liquid.
Toss. Take the dried shrimp and toss them in the spice bowl.
Batches. If the pan is large enough, you should be able to cook the shrimp in two batches - don't crowd the shrimp. Leave some space between each. If you have a smaller pan, cook in more batches.
Cook. Heat 1 tablespoon of olive oil in the pan over medium high heat. Place half the shrimp in the hot pan, cooking one side of the shrimp for 1-2 minutes, then flip each and cook for another. The trick is to cook the shrimp through, but not overcook. The larger the shrimp, the easier this is to manage. When cooked, the shrimp should be opaque (not translucent) and slightly firm when pressed.
2 tablespoons olive oil (for cooking). Additional oil needed for tortillas, see garnish.
Repeat. Repeat this process until all the shrimp are cooked.
