Prepare Barbecue Sauce. Add shredded chicken to sauce. Heat through, stirring frequently. Serve on split buns. If desired, serve with red onion slices and dill pickle spears.

Barbecue Sauce: In a medium saucepan heat 1 tablespoon olive oil over medium heat. Add 1/4 cup finely chopped onion; cook 3 to 5 minutes or until tender, stirring occasionally. Add one 8-ounce can tomato sauce, 2 tablespoons tomato paste, 1 tablespoon Dijon-style mustard, 1 tablespoon Worcestershire sauce, and 1 teaspoon honey or heat-stable granular sugar substitute (Splenda). Bring to boiling; reduce heat. Simmer, uncovered, about 5 minutes or until desired consistency. Season to taste with salt and pepper.
