Well, I usually do my roast like this: (It's really easy!)
I place the roast in the crockpot, put an envelope of Lipton Recipe Secrets, Beefy Onion --- (Recipe soup mix) over the roast. Add potatoes and carrots (sometimes I'll add green beans or peas.) I use whatever is on hand. Sometimes I use fresh produce or canned it doesn't really matter, it always turns out great.

I add about about a cup & 1/2 of water give or take, (Depends on if I use canned veggies --- then I'll use some of the liquid from that.) If it's a large roast I'll put the crockpot on high for about 3-4 hours, then turn the temp down to low for another 3-4 hours or so.
I use the leftover beef for BBQ (Shred some and marinade in BBQ sauce for at least 3-4 hours prior to heating).Or I'll make a stew or soup by dicing the meat, adding veggies, & adding beef broth (or the liquid from the roast earlier) or tomatoes (depends on if it's a stew or soup you want), sometimes I'll add alittle diced onion and let it simmer in the crockpot. It's fun to play around and experiment. I always add a little of this and alittle of that.
For chili:
I brown about a pound of hamburger (---sometimes I'll add green pepper and onion to the hamburger as it cooks-- that's if I don't use the Chili Tomato Sauce) , drain and put in the crockpot. I add 1 can (about 14 oz) of Hunts Chili Tomato sauce, then I add 1 can of Hunts Diced Tomato, with Basil, Garlic and Oregano (I love that stuff!), and I add one can of kidney beans (drained and rinsed). Set the crockpot on low and let it cook for about 8 hours. I like to serve it in a bowl with Fritos and sour cream, and shredded cheddar cheese.
If there are leftovers I have it later in the week over a baked potato with the sour cream and shredded cheese. Or maybe I'll use it for Tacos, or over noodles.
I love the crockpot because it frees me up to do other things.
That's a start!
