Before sandwiching the ingredients, put them into the bento box and cut if needed to accommodate the box's width.
Put the sandwich ingredients on a slice of sandwich bread.
Roll it up.
Use cut out triangles of bread for the ears, nori seaweed or konbu for the whiskers and eyes, and cheese or a vegetable sheet for the nose.
Put the parts on the bread to finish!

Story Behind this Recipe
I made these sandwiches for my daughter's lunch.
You can add your own flairs to these sandwiches with toppings and ingredients of your choice. If it's difficult to keep the facial features glued on, use a little bit of mayonnaise to help glue them on.
