Here's a cute and easy was to make snail shaped sandwiches for your kids bento box. This mom used a sandwich press or cookie cutter to make heart shaped sandwiches. Put the heart on it's side and decorate the face. Use raw spaghetti, nori seaweed, and kameboko(fish paste cakes) or cheese. Use a colorful food for the cheeks, tomato or crab stick skins are good substitutes. The shells are circles of two different colored cheese.
