Hobo stew was made for me once by a brief boyfriend I had, but easily found it's way into the family menu. It's easy to make, not full of starches, and easy on the budget. Even if you are frequenting your local food pantry, you will often find you have most if not all of the ingredients already in your kitchen cupboards, and it's a snap to make.
1 yellow onion, cut into small-ish pieces (can double if you like)
1 bell pepper, diced or cut in strips to taste (can double if you like)
1lb medium lean hamburger (you don't' want a lot of grease, but don't spend more than you have to - pour off the grease if you must.)
4 cans of any brand of cheap pork and beans
1 to 1 and1/2 cups Heinz ketchup or BBQ sauce
The first thing to do is pour a tiny bit of oil in a skillet and cook up those onions and peppers. Take them out, and cook up your hamburger until it's no longer pink, and maybe a nice brown. Throw the onions and peppers back in, add in the rest of the ingredients, and simmer until nice and hot.
You don't want this to be too soupy, so only put as much ketchup as you need. There's a lot of things you can throw into this - use your imagination.
