Preheat your oven to 375°F and line a baking dish with parchment paper.
Slice the bell peppers in half lengthwise and remove the seeds and internal ribs.
In a large skillet over medium heat, cook the ground turkey until it is fully browned and no longer pink.
Add the minced garlic, dried oregano, sea salt, and black pepper to the skillet, stirring for one minute.
Incorporate the cauliflower rice, tomato paste, and diced salami into the turkey mixture until thoroughly combined.
Arrange the pepper halves in the prepared baking dish and fill each cavity generously with the turkey and salami mixture.
Cover the dish tightly with foil and bake for 25 minutes until the peppers are tender.
Remove the foil, top each pepper with shredded provolone cheese, and bake for an additional 5 minutes until the cheese is bubbly and golden.
