01 - Preheat oven to 375°F. Lightly grease a baking dish sized to accommodate peppers standing upright.
02 - Bring a large pot of salted water to a boil. Blanch peppers for 3 to 4 minutes until slightly softened. Drain thoroughly and arrange cut side up.
03 - Heat olive oil in a large skillet over medium heat. Add onion and cook 3 minutes until translucent. Add minced garlic and sauté 1 minute until fragrant.
04 - Add ground turkey to the skillet. Cook while breaking apart with a spoon for 6 to 8 minutes until thoroughly browned and cooked through.
05 - Stir in drained diced tomatoes, cooked rice, oregano, basil, paprika, salt, and pepper. Simmer 3 to 4 minutes to meld flavors. Remove from heat and fold in half the shredded cheese.
06 - Distribute turkey and rice mixture evenly among prepared bell peppers. Arrange peppers upright in the baking dish.
07 - Crown each stuffed pepper with remaining shredded cheese.
08 - Cover baking dish with aluminum foil and bake 25 minutes. Remove foil and bake an additional 10 minutes until cheese melts and turns golden brown.
