Start by heating the olive oil in a large skillet over medium heat.
Toss in the diced onions, letting them cook for about 2-3 minutes until they start to soften.
Stir in the chopped red bell pepper and minced garlic. Continue cooking for another 3 minutes.
Next, add the ground turkey into the skillet. Break it apart and let it brown.
Once the turkey is nicely browned, stir in the black beans.
Add the BBQ sauce, Worcestershire sauce, and tomato paste, ensuring everything blends seamlessly.
Let the High Protein BBQ Sloppy Joe mixture simmer for about 10 minutes, allowing the flavors to meld.
Season with salt and pepper according to your preference.
Once done, divide the mixture and serve it onto the whole grain buns.
