Easy, Yummy, Sloppy Joes

I'm not sure where my mom picked up this recipe for sloppy joes, but they're way easy, and not your traditional joe.

~Brown and drain 1 lb. of hamburger
~Pour in one can of Campbell's Chicken Gumbo soup
~Add 1 cup of ketchup (more or less to taste)
~Add 1/4 cup of mustard (more or less to taste)
~Simmer 5 minutes
~Eat!
