A very popular and very spicy Szechwan noodle dish. Easy and fun to make! I like to add a little garlic to this when I make it. About a tablespoon or so. If you prefer less spicy food, omit the green and red chili peppers. The dish is delicious even without them. The Spicy Bean Sauce (AKA Ma Po Sauce) isn't actually very "hot" at all, but definitely do not omit this ingredient! You will probably need to go to an asian market for this one. The only type I'm able to find is by Lee Kum Kee. UPC 0-78895-61000-0. Chinese chili sauce (Siracha) also works in a pinch. Serve with some rice and enjoy!
