This is one of our favorite:
6 Beef Cube Steaks
1 Onion, thick-sliced
3 cups water
3 gravy mixes
Put the cube steaks, onion, and 1 cup water in the crock pot on low in the morning. When you get home, add the other 2 cups water and the gravy mixes. Make the rice and veggies while the meat cooks for the last 20 minutes. Even my kids like this one!!
If you want a smaller recipe just remember 1 gravy mix for each cup of water. I get the steaks and gravy mixes at our local Aldis or Save-A-Lot and it is an economical meal.
