Layer bell peppers and onions on the bottom. Add garlic, chicken, Italian seasoning, salt, pepper, Worcestershire, and broth. Drizzle with olive oil if using.
Let It Cook
Cover and cook on low for 6–7 hrs or high for 3–4 hrs, until chicken is fork-tender.
Shred & Stir
Shred chicken with two forks right in the slow cooker. Mix everything together so it soaks up all the juices. Adjust seasoning if needed.
Build the Sandwiches
Toast rolls with butter (optional but recommended). Pile on the chicken-pepper mixture and top with 2 slices of provolone.
Melt the Cheese
Broil sandwiches for 1–2 minutes until cheese is melted and bubbly. Serve warm!
Notes
Use chicken thighs or even rotisserie chicken (reduce cook time).
Try mozzarella, Swiss, or pepper jack if you’re not into provolone.
