Prepare tortillas by spreading a light layer (about 1 tablespoon) of remoulade or mayo on one side. This will act as your "glue" for the fillings. Set aside.
Heat oil in non-stick skillet over medium heat. Add onion, garlic, shrimp, and seasonings; saute about 2-3 minutes or until shrimp turn pink. Remove shrimp mixture from pan and place in bowl. Combine with crumbled bacon and pickled jalapenos. Taste to make sure seasonings are how you want them.
If necessary, spray pan with non-stick spray.
Place tortilla in pan, clean side down. On half of the tortilla,layer in 1/3 of cheddar cheese, then 1/3 shrimp mixture, then 1/3 of the jack or mozzarella cheese. Fold empty side of tortilla over the fillings and press down.
Let tortilla brown until crisp, about 4-5 minutes. Flip and brown the other side.
Repeat with remaining tortillas. Cut each folded quesadilla in half when ready to serve.
Serve with your choice of sour cream, guacamole, salsa, or all three!
