In a large skillet (an iron skillet preferably), add some butter and saute the onions and bell peppers.
2 tbsp unsalted butter, ½ med onion, 1 med bell pepper
Cook until soft for about 2 minutes. Add the shrimp and cook for another 3 to 4 minutes or until the shrimp is no longer translucent. Note: Make sure not to overcook the shrimp as it can become rubbery.
1 lb shrimp
Assemble the tacos by adding a layer of shrimp and top it with shredded cheese.
2 cup queso quesadilla cheese, 10 corn tortillas
In the same skillet, melt some butter with 1 tablespoon of olive oil. Place the tacos open to warm up the entire tortilla.
1 tbsp olive oil, 2 tbsp unsalted butter
As soon as the tortilla becomes soft, using a spatula, fold it to cover the shrimp side.
Flip the tacos to brown the other side. Cook until crispy and the cheese has melted. Repeat the process until all tacos are done.
