I've been playing around with my crock pot, but threw together this one and decided I LOVE it!
In a crock pot, cut to bite-sized pieces and mix
1 lb. beef
a few carrots
one small onion or half a large one
three or four stalks of celery
2 peeled apples, preferably a type that cooks well (like Fuji)
Add one can of frozen apple juice, and just enough water to cover everything that's in there. Throw in 1/2 teaspoon cinnamon, and cook until dinnertime (varies by crock pot type and how hot it is).
The resulting beef stew is just a little bit sweet, and the beef, onion, and celery especially pick up the apple cinnamon taste. It also reheats well!
