Use a baby chick cookie cutter to cut the hanpen, then cut off the chick's bill.
Add butter to a pan and fry the hanpen until it's slightly browned.
Take the fried hanpen, and slice in half. Punch faces out of nori seaweed and use a straw to punch out cheeks from a slice of ham.
Sandwich the cheese between two reversed identical pieces.
Sandwich the parts as shown and they're done. (If the nori parts are too loose, use mayonnaise to stick them on like glue.)
This is how they look packed in a bento.
