Hi Sarah Jane,
This is one of my favorites:
5 lbs beef roast
1 can cream of mushroom soup (I substitute cream of celery because hubby hates mushrooms)
1 can onion soup
1 medium size coca cola
salt to taste
pepper to taste

Salt and pepper roast. Place in roaster or wrap in foil.
Cook about 1 to 2 hrs, depending on size of roast. Remove from oven and add soups and coca cola. Return to oven and cook 1 to 2 hours more. This makes a thick brown gravy. Serve gravy over potatoes or rice.
Start the roast cooking on 450 degrees and then turn it down and cook on 350 degrees until tender.
If gravy gets thick, add more coca cola.

This is good stuff!
Trish
