A staple of Asian food culture, the humble noodle is one of the most nourishing ''fast foods'' on earth. Eaten with a simple bowl of soup or with stir fried meat or vegetables, noodles provide a cheap, quick, and healthy food alternative. These unusual noodles are made with black rice-a deep purple colored rice with a nutty flavor which is rich in minerals and fiber. Try these noodles with mixed mushrooms a lightly fried and garlic and spring onions. Add tofu or a little meat as required.
