I tried this last night. Turned out pretty good.
3lbs ground beef
Onion - diced
Garlic - minced
Hot sauce - to taste
Combine and brown in a skillet. Drain beef, return to pan. Stir in Steak sauce and bar-b-que sauce (tomato sauce can be used instead). Stir in your favorite LC veggie. ( I used broccoli). Place entire mixture in casserole dish. Top with Mock Mashed Potatoes. Sprinkle with Cheddar. Bake uncovered for 40 min at 350.
