A tender, melt-in-your-mouth main dish. Nice with a baked potato and green salad.
Place steaks in a large roasting pan.
Sprinkle with onion soup mix and bake at 350 degrees Fahrenheit for two hours, tightly covered.
Heat oil in a small saucepan. Sauté onions and mushrooms until soft.
In a small bowl, combine teriyaki sauce, vinegar, sugar, salt, pepper, and garlic powder to form a sauce.
Top steaks with mushrooms and onions, then pour the sauce over it.
Cover; bake at 250 degrees Fahrenheit for one more hour.
