Earth Balance has a soy-free margarine.

Spectrum has a palm oil shortening, if you're willing to use palm oil.

You'd have to ask the other parent if they are comfortable with those products.

Enjoy Life chocolate chips/chunks are Top 8 free--no lecithin.

My cookies are all GF, so I won't bother sharing recipes 

This looks promising:

I am making cookies for all of the drama kids at the high school, for their dress rehearsal night on Tuesday.  All of the drama booster parents provide a meal for dress rehearsal, and I signed up for dessert.  My two kids have allergies to milk, eggs, peanuts, and tree nuts --- so we are making cookies that are safe for my kids.

One other student has a peanut and soy allergy, and his mom avoids all soy, including soybean oil and soy lecithin.

Does anyone have a cookie recipe that does not use soy?  I would like to avoid milk and eggs as well so that my kids can eat them, too.

My margarine has soy and my shortening has soy.  Need to figure out something else.
