Spray a large skillet with nonstick spray and bring it to medium-high heat on the stove. Add turkey and sprinkle with steak seasoning and salt. Cook and crumble until it's mostly cooked, about 8 minutes.
Reduce the heat to medium. Add onion, bell pepper, Worcestershire sauce, and vinegar. Mix it well and continue to cook and crumble until the meat is fully cooked, about 5 minutes.
Reduce the heat to low. Add tomato sauces, tomato paste, and sugar. Stir well. Stirring occasionally, cook until it's hot, about 5 minutes.
Toast the buns, if desired. Evenly distribute the mixture among the bottom buns and then finish off with the tops of the buns. Enjoy!
