BBQ (as from Idaho and Utah); Sloppy Joes to everyone else!

I recently lost a recipe that was at one time a staple in my children's lives....the BBQ recipe. First I feel the need to explain; when you live in Idaho and Utah, bbq is a sloppy joe. I know that everyone from the other states will know what that is and that bbq has other meanings in different areas of the country. Sloppy joes were the one thing that all five of my kids could agree on at one time. They ate them at family get-togethers, winter or summer nights, and when there were a LOT of friends coming over for dinner. I was craving them the other night and searched high and low for my treasured recipe. I sent a text to my friend's daughter (my friend gave me the original recipe, but she was at work), I then sent a text to her husband at their home; no dice! I then searched my numerous recipe books for a similar recipe and finally found one. I really had to modify it and taste test the sauce, but I feel I had come up with a respectable facsimile. My friend came over that night and the smell that hit her as she walked through my door was a great one. She stirred, she tasted, she ended up taking a "to go box" home for dinner the next night! Picky eaters are sure to love this recipe and you can feel good about the veggies they are getting along with the protein. 3lbs browned ground beef; 1 diced onion; 2 stalks diced celery; 2 grated carrots; 1 diced green pepper; mix well and put into your crock pot. Mix 2 14oz cans of tomato sauce; 4 cloves minced garlic (I use the bottled minced garlic); 3/4 t salt; 3/4 t pepper; 1/4c balsamic vinegar; 1/2c brown sugar; 1T Worcestershire sauce; 1T brown mustard; pour over crock pot mixture and stir to evenly coat. Cook on low 5 hours or high 3 hours. Serve on hamburger buns or bread. I like to add a tossed salad or potato salad with veggies sticks and dip to the meal. If you happen to have left overs; they freeze really well!
