Spray slow cooker with non-stick cooking spray. Place chicken inside slow cooker, place butter on top of chicken and pour chicken broth on top. Layer sliced green peppers, sliced onion, garlic, Italian dressing mix, paprika, salt and pepper on top of chicken.
Cover and cook on low for 6-7 hours (or high for 3-4 hours).
When chicken is done cooking, remove from slow cooker and shred (it should fall apart pretty easily). Return shredded chicken into liquid in the slow cooker.
Spoon shredded chicken onto buns and top with pieces of cheese. Another yummy option is to toast your bread in a 375℉ oven for 4-5 minutes, then top with meat and cheese and stick back in the oven for 5 minutes to melt the cheese and make it nice and gooey.
Notes
To make this a freezer meal, place all ingredients in a resealable gallon-sized freezer bag. Mix together and zip bag closed. When ready to eat, remove from freezer and thaw in fridge for 24 hours. Spray slow cooker with non-stick cooking spray. Pour contents of bag inside the slow cooker. Cover and cook on low for 6-7 hours (or high for 3-4 hours). Spoon meat mixture onto hoagie buns and top with pieces of cheese.If you wanted to, you could also throw some fresh sliced mushrooms into the slow cooker with the chicken.My sister and I discovered that we loved Dijon mustard on the bread for an additional kick.
