Finely dice the yellow onion and green bell pepper; mince the garlic clove.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the diced onion and bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables are softened and translucent.
Add the ground turkey to the pan, using a wooden spoon or spatula to break the meat into small crumbles as it browns.
Once the turkey is no longer pink, stir in the minced garlic and cook for an additional 60 seconds until fragrant.
Reduce the heat to medium-low and pour in the tomato puree, apple cider vinegar, yellow mustard, and coconut aminos.
Season the mixture with smoked paprika, sea salt, and black pepper, stirring well to combine all flavors.
Allow the mixture to simmer for 5-8 minutes, stirring occasionally, until the sauce has thickened and beautifully coats the turkey.
While the meat simmers, lightly toast the whole wheat bun in a separate pan or toaster until golden.
Spoon the warm sloppy joe mixture onto the bottom half of the toasted bun, top with the other half, and serve immediately.
