1 medium Granny Smith apple, peeled, thinly sliced
1 small sweet onion, thinly sliced
1 1/2 tablespoons packed brown sugar
1 (13.8-oz.) can Pillsbury® refrigerated classic pizza crust
4 (1-oz.) slices provolone cheese, each cut into quarters
1 cup refrigerated honey hickory barbecue sauce with shredded chicken (from 18-oz. container)
4 oz. marbled mild Cheddar and white Cheddar cheese blend, cut into 12 slices
1 egg white, beaten

Heat oven to 425°F.

Spray large cookie sheet and 10-inch nonstick skillet with cooking spray. Add apple and onion to skillet; cook over medium heat, stirring occasionally, until apple is tender and onion is translucent. Stir in brown sugar. Cook and stir an additional 2 minutes. Remove from heat.

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