In a medium-sized bowl, lightly season shrimp with salt, ground black pepper, and 1 tbsp. of chili powder. Mix and marinate in the refrigerator for 10 minutes.
In the meantime heat 2 tbsp. of oil on medium-high heat in a large skillet or pan. Add onion, bell pepper, and garlic and cook until tender (about 3 minutes).
Add the corn, black beans, chipotle, and ancho hot sauce remaining chili powder, ground cumin, dried oregano, 1 tbsp. of salt, 1 tsp of ground black pepper, and lime juice. Mix and cook for about 3 minutes. Stir occasionally to prevent burning.
Add the seasoned shrimp and cook for another 2 -3 minutes or until the shrimp begins to turn pink mixing every minute for even cooking.
Transfer the mixture to a bowl and clean your skillet before placing it back on the heat. Spray the pan with non-stick spray and place a tortilla in the pan and sprinkle cheese on one side.
Divide shrimp mixture into thirds and add 1/3 on top of the cheese.
