Crockpot Sloppy Joes

This was a crowd pleaser, with 2 of my men having seconds, and one had thirds! The photo shows what was left by the time I tried to get a photo!
I made 1 lb of meat, but there was a TON of sauce, and my husband suggested I make 2 lbs next time.  I think this would make great leftovers.

Ingredients
2 lb. ground beef or turkey
8 oz tomato sauce
 1/4 cup brown sugar
 1 cup BBQ sauce
 1/2 cup ketchup
 1/2 cup water
 2 Tbsp cider vinegar
 2 Tbsp mustard
 Instructions:
Brown ground beef or turkey until cooked and drain. Place beef or turkey in the crock pot and add all remaining ingredients. Stir well. Cook on low for 4-6 hours.
Serve on your favorite hamburger buns.
