Try calling Amorette's and asking if they can accommodate a dye-free dessert. Looking at their menu, there are not pies but there were some options that seem like they may fit the bill. As a fellow mom of a dye-free child, I commiserate with the struggle. My DS "only" reacts behaviorally as opposed to hives or other physical reactions and artificial dyes really are in SO many things. In fact, I found a large bag of naturally colored peanut M&M's on
amazon and am wrapping it up for him for Christmas and I honestly think that will be the gift that has the most wow-factor for him
