The Food Allergy Network has their read a label cards with ingredients that soy
may be hidden as.

A Great starting point - make a list of foods she can eat.  Then figure out how
to combine them.

Cookbooks -  Beth Kidder's   Milk Free Kitchen has good recipes in it and most
without soy.    At many libraries.  Most other allergy cookbooks I have are wheat
free recipes.
