BBQ Chicken Sandwiches
6 chicken breasts (about 3 1/2 pounds)
1 (12 ounce) bottle Sweet Baby Rays BBQ Sauce
2 T Worcestershire sauce
1/2 C Kraft Zesty Italian Dressing
1/4 C brown sugar
8 hamburger buns
8 slices Swiss or provolone cheese (optional, but really tasty!)

Add 1 (12 ounce) bottle of sweet baby rays bbq sauce, or 1 1/2 cups worth. Pour it into a medium-sized bowl.  Add 2 tablespoons Worcestershire sauce,  1/2 cup Zesty Italian Dressing, and 1/4 C brown sugar. Take a whisk and stir it all together to combine.  Place 6 chicken breasts (about 3 1/2 pounds) in to crock pot. Pour the sauce over the top. Cover and cook on low for 7 hours or on high for 3 1/2-4 hours.  Pull chicken out and shredded it up. Then place it back into the crock pot and give everything a nice stir, allowing the chicken to get well coated. Serve on Hamburger buns with a slice of provolone or Swiss cheese.
