Preheat oven to 400°F (200°C).

Lightly flour a surface.

Roll out the pizza crust into a 12x9-inch rectangle.

Brush the crust with honey barbecue sauce.

Layer the crust with mozzarella cheese, shredded cooked chicken breast, finely chopped red onion, and minced fresh cilantro.

Sprinkle with Italian seasoning (optional).

Roll up the crust jelly-roll style, starting with a long side.

Pinch the seams to seal the roll.

Place the roll seam side down on a baking sheet coated with cooking spray.

In a small bowl, beat egg white and water.

Brush the egg white mixture over the top of the roll.

Sprinkle with garlic powder.

Bake for 15-20 minutes, or until lightly browned.

Cool for 10 minutes before slicing into desired serving sizes.
