1/2 cup honey hickory barbecue sauce
1 cup shredded chicken
4 oz. marbled mild Cheddar and white Cheddar cheese blend, cut into 12 slices

1. Heat oven to 425°F. Spray large cookie sheet and 10-inch nonstick skillet with cooking spray.

Spoon barbecue sauce with shredded chicken over cheese. Layer apple-onion mixture over chicken. Arrange Cheddar cheese blend slices evenly over apple-onion mixture.
