Erin's Recipes for People Who Can't Cook: Bean Pot

I'm pretty sure this, like Tater Tot Casserole, falls under the heading of White Trash Cuisine, but I like it and it's easy, so why not?

1 lb. ground beef
1 med. onion, diced
3 15-oz. cans pork and beans (pork optional)
3/4ish c. brown sugar (I hate things that call for 3/4 c. because I don't have a 3/4 c. measure. I usually just eyeball it in a 1 c. measure)
1/4 c. molasses
2/3 c. ketchup (I do, however, have a 2/3 c. measure. I know, random.)
1 tbsp. prepared mustard

Brown and drain beef and onion. Add all the other ingredients. Bake uncovered at 325 degrees F for 1 hour, stirring occasionally.

Whee, meals for a week!
