1. Combine the flour with the mustard, then coat chicken with mixture. Brown coated chicken breasts in hot oil in a large skillet then put in crock pot.
2. Pour soup and water into crock pot. Cook, covered, on low for 7 hours.
If you like simple chicken dishes, not too fussy, not too bland, this is a great recipe to try out on your family. Serve these chicken breasts alongside a nice, big salad and your meal is complete. You may also want a side of brown rice or whole grain pasta. The tangy dry mustard flavor is a nice contrast to any sort of sweet salad, perhaps with diced red bell peppers on top. Even a fruit salad goes nicely. Lots of options for you to try! Enjoy!
