4-6 lbs. chicken, bone-in works best (dark or white meat)
3-4 cloves garlic
1/4 medium onion

Put chicken, onion, and garlic into crockpot, cover with water and cook until meat starts to fall off the bone. (About 6-8 hours on low).
Drain off water into large bowl (and save to use in place of store bought chicken stock/broth), remove skin and bones. With 2 forks, gently pull the chicken apart.

Meal Ideas:

Add BBQ Sauce and serve as Pulled Chicken (great for sammies).
Add in some tomato sauce, garlic salt, onion powder, and taco seasoning for Chicken Tacos, Chicken Enchiladas, Chicken Quesadillas, and Chicken Burritos.
Serve over pasta.
Mix with cooked, diced potatoes as a hash
Use in place of lunchmeat
Add to broth, with noodles and veggies for homemade chicken noodle soup
Add into boxed pastas/rices/potatoes, for an entree on a side-dish budget!
Make mashed potatoes, make packaged gravy mix and add in chicken. Serve chicken in gravy over potatoes.
Makes a great pizza topping.

This freezes very well, and helps out in a pinch when you didn't plan dinner or forgot to thaw something. Instead of buying pricey cans of chicken breast meat, this is a great, cheap substitution.
