I have tons of recipes tried and true recipes using chicken that will work using cooked chicken, too. We love chicken so I cook A LOT with it.
Some of my recipes here at FC and on my blog:
crockpot chicken stew - cook everything without the chicken and then stir in chicken in the last 1/2 hr. to let it warm up.
4 ingredient chicken casserole is great on a chilly night.
Chicken Tortilla Soup Tomato Chilie Chicken over Egg Noodles Chicken Chimis - little chicken pockets...very easy!
Chicken and Mushroom Penne Crockpot Chicken and Stuffing - again, quick and easy. Cook without chicken and add it at the end.
Chicken Enchilada Casserole Crockpot Chicken Italiano
There's even more on my blog if you go
here and search "chicken" and "crockpot", too!
Can't wait to see what recipes other share, too!
