This is exactly my kind of recipe -- beyond simple, but definitely good.
In the morning, throw a few chicken breasts into the crockpot. Top with salsa -- a fancy kind, or just whatever is in your fridge. Cook on low for about 8 hours.
I don't like salsa, so I pour it into a separate bowl for my husband. Then I shred the chicken and throw it in a tortilla shell with sour cream, shredded lettuce and grated cheese. You, of course, can add whatever toppings you like. My husband drenches his in the salsa.
We made two large chicken breasts yesterday; we've made six large tacos from it and still have only used about half the chicken. It makes amazing leftovers -- I don't even bother to heat it up.
Try it and let me know what you think.
