Directions:Jenise: I love peas and beans more than most people, so tofu is a natural choice for me． My Chinese friend Annabelle loves them too, and tells me that soy beans contain an ingredient not present in any other food source, or at least in that concentration, that helps prevent breast cancer． When we share a big bowl of these, we eat with abandon "for medicinal purposes"!

Within the earth there are roots and seeds: on the bare twigs, there are winter buds: buried in soil and mud beneath ice-locked water are the turtles and frogs and dragonfly nymphs: hidden in decaying logs and under snowcovered debris are the fertilized queens of the wasps and blumblebees. Everywhere ,on all sides of us. as far as winter reigns. life is suspended temporarilv. But it has not succumbed. It is merely dormant for the time being, merely waiting for the magic touch of sating. All the blooms o
