Homemade sloppy joes

I am not a fan of sweet/savory foods, but this one won my heart.  I combined a bunch of recipes for Sloppy Joes and gave it a twist.  I served these on Hawaiin sanswich buns.  But this could have worked on any bread rolls if it's too sweet.

1 pound of cooked and drained hamburger/ground beef. *See note below
1 small onion, diced finely
1 rib of celery, diced finely
1-2 cloves of garlic, minced finely
1 cup of ketchup
2 tbsp of worcheshire sauce
2 thsp of teriyaki sauce
2 tbsp of cider vinegar
2 tbsp of brown sugar
1 tsp of onion powder
1 tsp of chili powder
1 tsp smoked spanish paprika
1/3 cup of water
Salt/Pepper to taste

Throw all in a crockpot, set it on low for 6 hours or high for 3 hours.  Serve over bread.  This is a "neater" sloppy joe, double everything except the meat if you want it really saucy.

*If your hamburger meat is the 93% fat free, you can throw it in with the with the rest of the ingredients without precooking and add an hour of cooking times.  I often do this to save the step of boiling and draining the fattier blends of hamburger meats.  If you do precook, I boil it for 25 minutes and drain since the fattier blends are more flavorful and cheaper.
