I got this recipe years ago from my sister in law. Actually, Jeff and I weren't even married when I got it.
This is a super easy one, and all 3 of my kids eat these sloppy joes:
1 lb hamburger (browned and drained)
1 can tomato soup
1 can chicken gumbo soup (this is getting a little difficult to find, so I bought some chicken and rice soup, but haven't tried it yet)
1 Tbs ketchup
1 tsp mustard
serve on bun, we like to put cheese on it too. If you are looking for a good whole wheat store bought hamburger bun, we really like Sara Lee's brand.
