I'm cooking a fancy picnic dinner for my mother's birthday. We're going to the theater and there are some tables outside. I want it to be special and I'm stuck for some reason! The meal has to be gluten free for allergies. Lower carb preferred for my mom's diabetes. Something that looks beautiful but can travel in Tupperware and will taste great lukewarm....My mom loves all cuisines and doesn't mind a little spice. help??
