Prepare the Skillet: Begin by heating a non-stick skillet over medium-low heat. Lightly coat the surface with cooking spray or olive oil to prevent sticking. Let the skillet warm up for about 1 minute.

Layer the Ingredients: Place one tortilla onto the heated skillet. On one half, layer half of the rotisserie chicken, part-skim mozzarella cheese, and a sprinkle of fresh basil.

Cook Until Melty: Allow the tortilla to cook for about 2-3 minutes until the cheese is melting and the underside of the tortilla begins to brown.

Fold and Finish Cooking: Gently fold the tortilla in half and flip it, cooking for another minute until it turns golden brown.

Slice and Serve: Transfer the quesadilla to a cutting board and cut it into halves or quarters for easy serving.
