Heat a large skillet over medium-high heat and add the ground turkey.

Cook the turkey for 5 to 7 minutes, breaking it into small crumbles with a spatula, until no longer pink.

Drain any excess fat from the skillet.

Add the diced onion and bell pepper to the skillet and sauté for 5 minutes until vegetables are tender.

Stir in the minced garlic and cook for 60 seconds until aromatic.

In a separate small bowl, whisk together tomato sauce, tomato paste, Worcestershire sauce, mustard, maple syrup, chili powder, smoked paprika, salt, and pepper.

Pour the sauce over the meat mixture and stir to incorporate fully.

Reduce the heat to low and simmer uncovered for 10 minutes, stirring occasionally, until the sauce thickens and coats the meat.

Serve the mixture warm on toasted whole wheat buns.
