Cut 3 slices of spam. Add a little oil to the frying pan and cook the spam until lightly browned on both sides.
Line the spam tin with plastic wrap. Scoop rice into the tin and gently press the rice together.
Pull out the plastic wrap and remove it. Place a slice of spam on the rice.
Cut out a strip of nori and wrap it around the spam-and-rice sandwich.
Use a nori punch or a pair of scissors, cut out pig’s eyes and nostrils from the nori sheet.
Cut out an oval shape from the slice of ham for the pig’s snout. Then cut out six smaller ovals for the pig’s ears and feet. Cut out an inverted “V” at the edges of four of the ovals to form the cloven hoovers.
Place the ham and nori on the spam.
Use a spaghetti noodle to secure the ham onto the spam and pack spam musubi into the bento box.
