Preheat your oven to 375°F (190°C). Slice off the tops of bell peppers and remove seeds.

Drizzle olive oil over the peppers and season with salt and pepper.

In a skillet, brown the ground turkey or beef over medium-high heat for about 5-7 minutes.

Sauté the diced onion for 3-4 minutes, then add minced garlic and cook for 30 seconds.

Mix in the drained diced tomatoes, tomato sauce, rice, Italian seasoning, smoked paprika, and red pepper flakes. Simmer for 5 minutes.

Remove from heat and stir in shredded mozzarella cheese and chopped basil.

Stuff the filling into each bell pepper and add water to the baking dish.

Cover with foil and bake for 35 minutes, then uncover and add remaining cheese. Bake for an additional 10 minutes.

Let the peppers rest for 5 minutes before serving.
