I'd really like to start making soup regularly. It makes a great take-to-work lunch and is really cheap to make. Do you have any recipes to share?

Some criteria for me:
-no meat, but chicken stock is ok
-I don't really like minestrone or pasta e fagioli types of soups. I'm more of a straight up tomato, squash, or mushroom type.
-Healthy is good, but if it tastes like diet food, no thanks!
