I frequently throw boneless chicken chunks into the crock pot with Pace Picante sauce. Of course I usually finish it with copious amounts of cheese but you can leave that out and it will still be tasty. Wrap it up in some lowfat tortillas.
Another crock pot favorite is boneless chunks cooked with lots of garlic, onions and peppers with a bit of broth. You don't need much you aren't going for soup. Then I serve it in pita with cucumbers, tomatoes and non fat greek yogurt.
