Slow Cooker Sloppy Joes

We love sloppy joes!  They're yummy, messy, and.... yummy!  These are so easy to make and they slow cook to perfection.  Delicious!  Enjoy!
-3 lbs lean or extra lean ground beef
-1 onion, finely chopped
-3 cloves garlic, minced
-1 red bell pepper, chopped
-1 1/4 cups ketchup
-5 Tbs Worcestershire sauce
-1/4 cup brown sugar
-3 Tbs apple cider vinegar
-3 Tbs yellow mustard
-2 tsp chili powder
-burger buns
In a large skillet (a wok will work great), brown the beef with the onion and garlic.  Once done, drain and set on your counter.  Stir in remaining ingredients, except for the buns.  Mix very well and pour mixture into your slow cooker.  Cover and cook on low for 4-5 hours (your house will smell amazing!).
Spoon onto burger buns.  Enjoy!
