Step 1

Prepare the sauce. In a mixing bowl, combine mayonnaise, jalapeños, jalapeño juice, sugar, cumin, paprika, cayenne pepper, and garlic powder. Whisk until smooth and well-combined. Adjust seasonings to taste.

Step 2

Grill chicken in vegetable oil. Cut into thin strips.

Step 3

Preheat the skillet over medium heat. Place the tortilla into the skillet and sprinkle it with 1/4 cup each of cheddar and Monterey Jack cheeses. Place 1/2 slice of American cheese on one side of the tortilla.

Step 4

Add 1/4 of the chicken over the American cheese. Spread 1 tablespoon of the sauce over the other half of the tortilla.

Step 5

Fold the tortilla over, sauce side up, with a spatula. Cook until the cheese is melted and the bottom side of the tortilla is toasted. Flip the tortilla over to toast the other side, about 30 seconds to 1 minute. Repeat the steps to cook all 4 quesadillas.

Step 6

Slice the quesadillas into triangles. Serve immediately and enjoy!
