Healthy Sloppy Joes

We tried this recipe yesterday, and loved it:

1 lb ground beef, bison, or turkey
2 c. wheat berries (wheat, cooked like rice in a little more than a two to one ratio)
1/2 onion chopped
2 garlic cloves, minced
2 sticks celery, chopped small
1 small carrot, minced
3-4 mushrooms, chopped semi-fine
1 1/2 tsp Worchestire sauce
1 T. vinegar
1 T. sugar
1/4 c. ketchup
8 oz tomato sauce or crushed tomatoes
salt and pepper to taste

Brown the beef, then add in the rest and cook until the veggies are soft. Eat on buns. Yum Yum.
