     When I was 13 years old, I became a vegetarian and quickly realized that I would have to learn how

to cook for myself. The first thing I ever asked my mom to teach me how to make was bean soup."Oh,

that's easy!" She told me. She started by explaining: "Almost every soup starts with onions and carrots."

     My mom is a chef who is able to cook delicious meals. She also told me that the very first thing she

had learned in cooking school was to make soup stock (拼盘)----followed by soup. Her teacher had told

the class: "If you learn anything here, it should be soup."

    In the US, soup isn't so much a part of a meal as a meal in itself. Soups are often made from the

leftovers (剩菜) of last night's dinner----a baked chicken or turkey can easily be made into a new meal by

adding broth (肉汤) and some vegetables. Soups are accompanied (伴随) by bread and topped with cheese.

    It was easy to impress my college roommates with my mom's great soup recipes (菜谱). Bean soup,

vegetable noodle soup, mushroom soup… For only a few dollars, three or four of us could eat well from

the same pot of soup for a whole week. Add a loaf of bread and some cheese, and our soup became a proper

feast (盛宴).

    I'm not a vegetarian any more, but I still make bean soup. It fills the house with lovely smells and reminds

me of my mom, and my home.
