Meanwhile, heat oil in large saucepan. Add garlic and mushrooms. Cook until lightly browned. Add greens. Stir well. Cover. Simmer 5 to 8 minutes. Drain pasta. Turn into large shallow bowl or deep platter. Add sauce and toss well. Add cheese and toss again. Garnish with red pepper strips, if desired. Serve hot with more cheese, if wished. Makes 4 servings.
