I love cooking pot roast (chuck roast), first thing when I get up in the morning before work I line the bottom of a slow cooker with peeled and cut up potatoes, add some baby carrots and a couple of celery stalks. Place the roast on top of all this with a few more carrots lined around the edge. Put a package of Lipton onion soup mix in a cup and mix with a can of swanson beef broth and pour over meat and veggies. Sprinkle with pepper. Cook all day on low while at work. When I get home the house smells wonderful, pull out your roast, if you can keep it from falling apart and put it on a platter circled with your veggies. Leave the juice in the bottom of the crock pot, add some cornstarch mixed with some water to the juice, turn crock pot on high and let simmer for a few minutes to thicken. Add some bread and there is supper. Very easy.
When you have some left put all in a container but defat the meat and cut in smaller pieces. Cut the potatoes and carrots in smaller pieces and pour gravy over all. The next night take the contents and pour into a skillet add a can of cream of mushroom and simmer, add some extra beef broth if needed but you want it thick. After heated all the way thru pour some on hot toasted bread and it is delicious the second night. My dad called the leftovers "Sh*t on a shingle" but it is so good!
