Crumbled Burgers

This recipe was passed down from my grandmother to my mom and now to me. They're kind of like a sloppy joe, except Mom always served them open-faced. I have two different versions of this recipe, one that was Granny's and one that Mom wrote for me (she changed Granny's recipe very slightly), so I'll post both and you can see which one you like the best!
