Here is a great crock pot stew.

2 lbs of stewing beef, cut into 1 inch pieces
5 medium potatoes, peeled and cut into 1 inch
pieces
4 carrots, peeled and cut
2 medium onions, sliced
3 celery stalks, cut
1 small turnip, cut into 1 inch pieces (optional)
1 can of beef broth

Coat beef in flour, do not brown meat, it will brown
in the crockpot.
Add all vegtables and stir. Pour beef broth over
mixture. It may not look like enough liquid but the
vegtables will also give off liquid so there
will be plenty. Cook on high 10-12 hours or on low
5-6.
