These cheesy nachos are a great way to use up leftover rotisserie chicken. Simply shred the chicken and mix it with some salsa. Spread some tortilla chips on a baking sheet, and top with the chicken mixture and some shredded cheese. Bake in the oven until the cheese is melted and bubbly. Serve the nachos with some sour cream and guacamole for a delicious snack or appetizer.
