Crock Pot Roast with Perfect Gravy

2 cans cream of mushroom soup
1 pkg dry onion soup mix (I just use onion flakes)
1/2 c. water (optional, I don't add this or it's too runny)
5 lb. roast

Mix soup, onion soup mix and water in crock-pot. Add meat and coat with soup mixture. Cook on low 8-9 hours (or high 3-4 hours). When it's done, take it out and strain the gravy into a serving bowl. It really is SO good and easy!
