Dairy-free cookie additivesI'm not sure about wheat and soy for these two, but at least you have a lead, if you haven't already tried these.
1. Ghiradelli SEMISWEET chocolate chips. (I don't have the package with me, so I don't remember whether it contains lecithin.)
2. Sunspire brand makes dairy-free chips. (Again, I don't have a package right here, so I'm not certain about the soy and wheat.)
