Spray a pot with cooking spray and place over medium heat. Mix together the brown sugar baking blend and the grill seasoning and set aside.
Brown the ground turkey and add the brown sugar/grill seasoning. Once the meat is cooked, add the onion, red peppers, vinegar, and Worcestershire sauce, cooking and stirring often until the vegetables are soft.
Add in the crushed tomatoes and tomato paste and stir until well combined. Reduce the heat to low, and continue cooking about five more minutes.
Serve over whole wheat pasta or on low calorie buns.
