Begin by slicing bell peppers and sweet onion into thin strips, and cut the chicken into smaller chunks.

In your slow cooker, add chopped chicken, bell peppers, and onion. Pour in Worcestershire sauce and enough broth to cover the ingredients. Sprinkle garlic powder and onion powder, then stir well.

Set your slow cooker to cook on low for 6-8 hours or on high for 3-4 hours.

Once done, use two forks to shred the chicken in the slow cooker, mixing with the veggies.

Toast hoagie rolls, spoon the mixture onto each roll, top with provolone cheese, and optionally melt it briefly in the slow cooker.
