I do something similar...except I buy a 5-7 lb roast and use a bottle of beer, a can of Cambell's beef consommé and a packet of Good Seasons. I stir everything but the beef together in the crockpot, then add the beef and add water until the roast is about halfway submerged.
We eat it in summer with on rolls served with potato salad or pasta salad. In the winter, we have whipped potatoes and another vegetable.
Leftovers: I take a square of Saran Wrap and scoop a sandwich-sized amount of beef into the middle of it. I wrap that up and freeze individually for sandwiches. It takes a few minutes to heat up (even from frozen) in a covered pan.
