When Rachel Berliner injured herself during pregnancy and could no longer cook healthful vegetarian meals, her husband, Andy, picked up some frozen dinners at a health-food store. Problem: "They tasted like cardboard," Andy recalls. Sensing a need, the couple took 100 hand-made vegetarian pot pies to a health-food show and started taking orders before they knew how to fill them. Twenty years later, Amy's Kitchen boasts 140 products and $240 million in sales. Amy, the baby who helped start it all, is now in college, training to take over the business.
