Add cream cheese, queso dip, and Rotel to the crockpot.
Cook on low for 6-8 hours or on high for 3-4 hours, or until chicken is easily shredded.
Shred chicken with two forks.
Heat vegetable oil in a large skillet over medium heat. Place one tortilla in the skillet, add a generous amount of chicken mixture to one half of the tortilla, and fold the other half over to create a quesadilla. Cook for 2-3 minutes per side, or until golden brown and cheese is melted. Repeat with remaining tortillas and chicken mixture.
Cut quesadillas into wedges and serve immediately.
Notes
Serve with your favorite toppings such as sour cream, salsa, or guacamole.
