Turkey Sloppy Joes

While visiting Brad and Erica in Springville, I thumbed through a cookbook she had with some yummy looking recipes. Here's the book: http://www.amazon.com/The-Family-Flavor-Practical-Delicious/dp/1484884043. The first I tried were the turkey sloppy joes, which I made in the crockpot. I initially used the food processor to mince all the veggies, so they ended up quite moist and also made the joes pretty runny. The next time I would either take some of the liquid out of the joes or just chop the veggies by hand.
1 8 oz can tomato sauce
2 T brown sugar
1 T dijon mustard
1 tsp apple cider vinegar
1 tsp worcestershire sauce
2 T olive oil
1 celery stalk, diced
1 green bell pepper, diced
1/2 yellow onion, diced
2 garlic cloves, minced
1 1/2 tsp kosher salt
1/2 tsp ground pepper
1 pound ground turkey breast
6 hamburger buns

In a medium bowl, combine tomato sauce, brown sugar, dijon mustard, vinegar, and worcestershire sauce. Whisk to combine and set aside.

In a large skillet over medium high heat, add olive oil. Once the oil is heated, add the celery, green bell pepper, onion, garlic, salt and pepper. Saute until veggies are softened, about 10 minutes. Add ground turkey. Break up the turkey and stir occasionally, about 5 minutes. Add tomato sauce mixture and stire well. Reduce heat and simmer for 5 minutes. Serve on buns.
