Round steak can be very tough, so it needs to be cooked low and slow. Here is a recipe that a friend of mine shared with me. It uses a crock pot and provides very tender and moist steak. You can even use frozen round steaks.
2 pounds of round steak (cut into individual portions)
1 14oz. can of diced tomatoes
2 garlic buds, finely minced
1 green pepper, chopped
1 rib of celery, sliced
1 yellow onion, diced
2 bay leaves
3 T Worcestershire sauce
pepper to taste
1 package of brown gravy mix
Spray crock pot with cooking spray. Add all ingredients except gravy mix. Cook on low for 6 hours. Stir in gravy mix and cook one more hour. Serve on rice or potatoes or for something different serve but delicious on top of cheesy grits. (That's my favorite)
