Preheat your oven to 375°F and line a small baking sheet with parchment paper.
Heat the olive oil in a small skillet over medium heat and sauté the diced yellow onion until soft and translucent.
In a medium mixing bowl, combine the ground turkey, sautéed onions, egg white, almond flour, garlic powder, sea salt, and black pepper.
Mix the ingredients gently with your hands until just incorporated, being careful not to overwork the meat.
Shape the turkey mixture into a compact rectangular loaf and place it on the prepared baking sheet.
Carefully wrap the bacon slices around the loaf, tucking the ends underneath to secure them.
Brush the top and sides of the loaf with one tablespoon of the sugar-free BBQ sauce.
Bake for 25 minutes, then remove from the oven and brush with the remaining tablespoon of BBQ sauce.
Return to the oven for another 10 minutes or until the internal temperature reaches 165°F and the bacon is crispy.
Let the meatloaf rest for 5 minutes before slicing to ensure the juices redistribute for a moist texture.
