Preheat the oven to 350°F. Place the shrimp on a sheet pan lined with parchment paper or a silicon baking sheet so they don’t stick. Season to taste with chili powder, cumin and salt and pepper. Bake for 5-6 minutes until they turn pink. Be careful not to overcook them. Let cool a few minutes.
Assemble the quesadillas -place some grated cheese on one half of the tortilla. Top with shrimp, corn, red pepper and more grated cheese. Fold over. Place on a baking sheet.
Bake for about 10 minutes at 350°F until cheese is melted. Then switch the oven to broil to crisp up the tortillas – watch carefully to prevent burning as they can crisp up quickly. Turn the quesadillas over to crisp the other side. This only takes 1-2 minutes per side.
Let cool 5 minutes. Cut into wedges. Serve with desired toppings.
