Preheat the Blackstone Grill over medium high heat (approximately 400 degrees F). Spread the vegetable oil onto the grill.

Place the chicken onto the grill in an even layer. Season it with the taco seasoning. Sauté the chicken for 3-4 minutes per side until it's browned slightly. Then top the chicken with salsa and toss the chicken to thoroughly coat the chicken with the salsa. Continue to cook the chicken until it's cooked through (internal temperature of 165 degrees F) for approximately 3-4 more minutes.

Push the chicken to one side of the grill. Reduce the Blackstone temperature to medium.

Place the tortillas on the grill. Top each tortillas a small amount of each cheese, then layer the chicken on top and then add more cheese. Carefully fold each the tortillas in half making a half moon shape.

Cook until one side of the tortilla is golden brown (1-2 minutes). Flip and then cook until the other side is golden brown as well (1-2 minutes). Watch them closely as they do brown quickly.

Remove the quesadillas onto a cutting board. Slice them and they they are ready to serve and enjoy!
