Crock Pot Sloppy Joes

Before getting started, you'll want to use a large knife to get all the veggies minced up.
In a large skillet over medium-low heat on the stovetop, cook the ground beef, minced celery, minced onions and minced green pepper 'til the beef is no longer pink and the veggies are soft and translucent.
Next, drain the grease out if necessary. To do this, scrape the meat all to one side of the pan, and then slightly tilt the pan downwards away from the meat, soaking up any excess grease with a paper towel.*
Once your meat mixture is fully cooked, add it to the CrockPot along with the ketchup, barbecue sauce, tomato sauce, brown sugar, mustard powder, Worcestershire sauce, vinegar, salt and pepper to taste.
Stir to combine with a wooden spoon, and then cook on low for about 2-3 hours, or 'til heated through.
Once your CrockPot sloppy joes are heated through, serve and enjoy on your favorite hamburger buns for dinner!
