frozen chicken breasts
1/3-1/2 c. dijon or honey mustard
1-3 Tb. water
Put all ingredients in a crock pot and cook until done. The longer it cooks, the more tender the chicken gets and the mellower the mustard flavor becomes.
I called it French Chicken because my kids hate mustard, but once it's been cooking for several hours, they couldn't really taste it. They just thought it was good.
