Ingredients
Salt
1/2 pound short whole wheat penne pasta
4 large red bell peppers, tops cut off and reserved, seeded
Black pepper
2 tablespoons extra virgin olive oil (EVOO), plus more for drizzling
4 jarred roasted red peppers
1 small red onion, finely chopped
2 cloves garlic, finely chopped
2 small portobello mushroom caps, chopped
1 teaspoon crushed red pepper
2 sprigs rosemary, stems discarded and leaves chopped
One can fire-roasted crushed or diced tomatoes (28 ounces)
2 cups arugula or baby spinach (a few generous handfuls)
1 cup basil leaves, loosely packed
1 cup grated Pecorino Romano cheese
Directions
Pre-heat the oven to 425°F. Bring a large pot of water to a boil, salt it, add the pasta and cook until al dente.
Trim the bottoms of the bell peppers, without cutting a hole, so that they stand. Season the insides with salt and black pepper. Turn the peppers bottom-side up in a 9-inch x 13-inch baking dish, set the tops alongside and drizzle with EVOO. Roast for 20 minutes.
Using a food processor, puree the roasted red peppers. In a large skillet, heat 2 tablespoons EVOO, two turns of the pan, over medium heat. Add the red onion, garlic, mushrooms, crushed red pepper and rosemary and cook until softened, 7 minutes. Stir in the pureed peppers and the fire-roasted tomatoes; season with salt and black pepper. Simmer for 5 minutes. Add the pasta and toss. Add the arugula and basil and cook until wilted.
Pre-heat the broiler. Turn the peppers upright; fill with pasta. Top with the cheese and broil until melted, 2 minutes. Cover with the tops and serve with any extra pasta.
