Edible rice papers are sold in Asian food aisle in supermarkets or Asian markets. Time Saving Tip: Use leftover rice from Chinese takeout to make these quicker. Make them the night before or prep all ingredients including chicken and carrot mixture so in the morning you just need to roll. The rolls can be wrapped in plastic wrap or placed in an air-tight container. The sauce can also be stored in a sealed container. Tuck the rolls and sauce into a lunch sack with a cold pack and send off to school.
