" Make the fillings: Combine the ricotta and Pecorino Romano cheeses, garlic, herbs, and egg with 1/2 teaspoon each of salt and pepper and the crushed red pepper in a bowl and set aside. Heat 1 tablespoon oil in a large skillet over medium-high heat. Add the mushrooms and cook until golden, about 3 minutes. Add the remaining tablespoon of oil, onions, and peppers and cook until slightly softened, about 4 more minutes. Add the spinach and remaining 1/2 teaspoon each of salt and pepper. Toss and cook until spinach is wilted and tender, about 2 minutes. Set aside. Assemble the lasagna: Heat oven to 350 degrees F. Pour 1 1/2 cups sauce into a deep-dish lasagna pan. Layer 5 lasagna noodles over the sauce. Top with half of the cooked vegetables and a third of the mozzarella. Layer with 5 more noodles and spread half the ricotta mixture over the noodles. Top with 1 cup of sauce and add another layer of noodles. Add the remaining vegetables, another third of the mozzarella, and a layer of noodles. Spread on the remaining ricotta mixture, 1 cup of sauce, and the last layer of noodles. Add the remaining sauce and mozzarella. Cover with foil and bake until bubbly, about 1 hour, 20 minutes. Let the lasagna cool slightly before serving."^^<http://www.w3.org/2001/XMLSchema#string>
