These stuffed bell peppers have a filling inspired by the Greek spinach pie, spanakopita, but you don't have to worry about working with phyllo, so they're great for an easy vegetarian dinner.
Preheat oven to 400 degrees F.
Heat 1 tablespoon oil in a large nonstick pan over medium-high heat. Add shallot and cook, stirring often, until softened, about 1 minute. Add spinach in batches and cook, stirring, until wilted, 3 to 5 minutes. Stir in dill, parsley, garlic and pepper. Cook, stirring, for 1 minute. Transfer the spinach mixture to a large mixing bowl. Stir in ricotta and feta.
Rub bell peppers with the remaining 1 tablespoon oil and sprinkle with salt. Divide the spinach mixture among the peppers and top each with 1 tablespoon mozzarella. Place in an 8-inch-square baking dish.
Bake until the peppers are tender, 30 to 35 minutes. Let cool for 5 minutes before serving.
