I cut it into pieces, make a brown gravy, add meat and either serve over bread, mashed potatoes or rice. Add a tossed salad and yum.
When I make pot roast, I make enough for left overs (there are only 2 of us). I add water to the pan drippings so I have enough liquid to cover the meat, I freeze the meat in meal size servings. I use the liquid in the brown gravy or in soup or stew and the meat goes in too. If I make soup first then freeze it, I don't add the noodles until I am ready to serve the soup -- again I freeze serving size portions.
