Prep your veggies: Finely dice the onion, bell pepper, and carrot so they blend into the sauce and soften quickly.
Brown the meat: Heat a large skillet over medium. Add olive oil if using turkey 99%. Add ground meat and cook, breaking up with a spatula, until no longer pink.
Drain excess fat if needed.
Sauté aromatics: Add onion, bell pepper, and carrot. Cook 5–6 minutes until softened. Stir in garlic and cook 30 seconds, until fragrant.
Build the sauce: Stir in tomato sauce, tomato paste, Worcestershire, apple cider vinegar, maple syrup or honey (if using), smoked paprika, chili powder, cumin, salt, and pepper.
Simmer to thicken: Reduce heat to low and simmer 8–12 minutes, stirring occasionally, until thick and glossy.
Taste and adjust salt, pepper, or vinegar.
Toast the buns: Lightly toast whole wheat or seeded buns for structure and flavor.
Assemble: Spoon a generous scoop of the mixture onto each bun. Add pickles, onion, or coleslaw if you like. Serve warm.
