Make a mixture of about 1/2 cup flour, salt, pepper and garlic to taste. Dip pieces of round steak in flour mixture. Pound floured steak pieces with a meat mallet.
Brown round steak in oil in a skillet. Add sliced onion and saute'. Put steak back in skillet along with onion. Add chopped tomato with liquid. Season with some garlic and pepper. Cover and simmer for 1 1/2 hours. When done add drained peas. I serve this with sour cream mashed potatoes. Put some sauce over the potatoes.
