I found this recipe in little booklet of recipes that came with my crockpot years ago. I tried it and loved it. I thought I would share.
1 1/2 lbs. pork steak, 1/2 inch thick, cut into strips
2 T. oil
1 large onion, sliced, 1 small green pepper, cut into strips
1 (4 oz) can mushrooms, drained
1 (8 oz) can tomato sauce
3 T. brown sugar
1 1/2 T. vinegar
1 1/2 tsp. salt
2 tsp. Worchestershire sauce
Brown pork strips in oil in a skillet to remove excess fat. Drain on double paper towels. Place pork strips and all remaining ingredients into a crockpot or slow simmering saucepan. Cover and cook on low for several hours (4-6) Serve over hot fluffy rice.
