Please be aware that ketchup has a good bit of added sugars- usually in the form of HFCS these days.

Alternately, you could use the sloppy joe recipe from Linda Sue's site. Granted it has a few more ingredients, so will take a little more time for measuring and mixing, but at least you're avoiding the added sugars.

Another alternative that's definitely not the sweet sloppy joe, but is pretty good is to make sloppy jose's. There are recipes out there that require lots of chopping and simmering, but the easiest thing to do is to use a no-sugar-added chunky salsa (1 cup for a pound of browned hamburger), then melt in a cup of shredded colby jack cheese. Different flavor, but very quick and easy.
