Lay out 2 tortillas on a clean work surface. Divide the cheese between each tortilla. Top with shrimp, mango and chives. Season with habanero lime spice. Top with remaining tortillas.
Heat 1 tsp. of the oil in a 12” skillet over medium heat. Add one quesadilla into the pan and top with 1 tsp. oil. Cook over medium heat turning halfway through cooking until tortilla is golden brown and heated through, about 1 ½ to 2 minutes on each side.
Repeat with remaining quesadilla. Cut quesadillas into 8 wedges and garnish with sour cream.
