Preparation Cook tortellini in large pot, drain and set aside. Heat oil in a heavy large saucepan over high heat. Add onion, prosciutto, garlic, dried red pepper and black pepper. Saute until onion is golden brown, about 10 minutes. Add wine and bring to a boil. Add mushrooms, bell pepper, green onion and peas and simmer until almost all liquid evaporates, about 5 minutes. Add cream and boil until sauce begins to thicken, about 5 minutes. Add tortellini, parsley, basil, and parmesan. Simmer until sauce coats pasta, about 4 minutes. Season to taste with salt and pepper. Transfer to large bowl and serve.
