01 - Preheat the oven to 375°F.
02 - Drizzle 1 tablespoon olive oil inside a baking dish large enough to hold the peppers upright.
03 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Sauté chopped onion until translucent, about 3 to 4 minutes. Add minced garlic and cook for 1 minute.
04 - Add ground beef to the skillet and cook until browned, breaking it apart with a spoon, approximately 5 to 6 minutes. Drain excess fat if necessary.
05 - Stir in quartered cherry tomatoes, cooked rice, oregano, cumin, smoked paprika, salt, and pepper. Cook for 3 minutes, then remove from heat.
06 - Fold crumbled feta cheese, chopped parsley, and mint into the mixture. Adjust seasoning as needed.
07 - Generously fill each bell pepper with the beef mixture and place them upright in the prepared baking dish.
08 - Pour the broth into the bottom of the baking dish around the peppers.
09 - Cover the dish with foil and bake for 30 minutes.
10 - Remove foil and bake for an additional 10 minutes until peppers are tender and tops are lightly browned.
11 - Allow the stuffed peppers to rest for 5 minutes before serving. Garnish with extra parsley, if desired.
