Preheat your oven to 375°F (190°C). Arrange the halved peppers cut side up in a baking dish and lightly brush them with a teaspoon of olive oil. Bake uncovered for about 10 minutes to soften the peppers slightly. The peppers should be fragrant and beginning to char around the edges.
Meanwhile, heat a tablespoon of olive oil in a sauté pan over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant, stirring constantly to prevent burning. The garlic should become aromatic and slightly golden.
Add the chopped sun-dried tomatoes to the pan and sauté for another 2 minutes. The mixture will become fragrant, and the tomatoes will soften slightly, releasing vibrant aromas.
In a mixing bowl, combine the cooked rice, sautéed sun-dried tomatoes, dried oregano, smoked paprika, and a pinch of salt and pepper. Mix everything thoroughly until the ingredients are evenly distributed and the mixture is moist but firm.
Carefully spoon the rice mixture into each of the parbaked pepper halves, pressing gently to fill them completely and create a rounded top. Ensure all peppers are evenly filled for uniform baking and presentation.
Sprinkle the shredded cheese evenly over the filled peppers. The cheese will melt and create a golden, bubbly crust, enhancing the flavor and visual appeal of the dish.
Place the filled peppers back in the oven, uncovered, and bake for an additional 20 minutes. The peppers should be soft, with the cheese melted and bubbling, and the edges slightly browned. Stop baking once you see a caramelized appearance on top.
Remove the dish from the oven and let the stuffed peppers rest for a few minutes. This helps the filling set and makes them easier to serve.
Garnish the peppers with freshly chopped herbs if desired, then serve warm. The peppers should be tender with a flavorful, cheesy filling and a slightly toasted top.
