BBQ Chicken Sandwiches

2 cups shredded cooked chicken
Sauce:
1/2 cup chopped onion
1/2 cup diced celery
1 garlic clove, minced
1 tablespoon butter
1/2 cup salsa
1/2 cup ketchup
2 tablespoons brown sugar
2 tablespoons cider vinegar
1 tablespoon Worcestershire sauce
1/2 teaspoon chili powder

1/4 teaspoon salt
1/8 teaspoon pepper

Cook and shred chicken; set aside. In a large saucepan, melt butter; sauté the onion, celery and garlic. Stir in the remaining sauce ingredients. Add chicken; stir. Heat mixture until hot and bubbly. Serve on toasted buns.

Note: Another good way to fix this is by spooning BBQ chicken onto buns and top with coleslaw.
