Cut one round steak into serving sized portions. Place in crock pot. Cover with a can or two of stewed tomatoes and one chopped onion. Cover and cook on high 3-4 hours or low for about 8 hours. My family likes this with mashed potatoes and a vegetable like corn, peas or green beans. This is a super easy meal because you don't even have to brown the meat before you put it in the crockpot.
I ended up not getting this started in time so I transferred it to my pressure cooker and it was done in about 20 minutes. I am going to start using my pressure cooker more often because it makes the food tender and it uses less fuel. Both of which are good things.
