I figured I would share one of my favorite and simple recipes...Sloppy Joes.

Brown up a pound of ground beef. (more if you need it) Drain grease from pan and put meat back in pan
Add 1 tablespoon of white vinegar and 1 tablespoon of sugar for EACH pound of meat.
Then pour ketchup on top till it looks like sloppy joes... stir
Then add whatever seasoning you like... I put nothing on mine but you might like other things

Here is the important part... turn heat way down, cover and simmer for 1 hour, stirring a few times

When I made this for the first time from a buddies recipe, I was like at first "blah, just plain sloppy joes" then after an hour of cooking the flavor really came out... or I was real hungry by then!

Good luck
