To Prep
Remove spam from can and wash the can. Let dry.
Slice the spam about 1cm thick.
In a medium bowl, mix the soy sauce, oyster sauce and sugar together. Stir until sugar is dissolved.
Place all sliced spam into the bowl, coat them evenly and marinate for 30 mins.
Cut some nori sheets into strips and some into the size of the spam.
To Cook
In a pan, place all the marinated spam in, pan fry on medium heat until the spam is evenly browned and slightly crispy on each side. Remove from heat and set aside.
To Assemble
Place cling wrap into the clean can, make sure there are excess cling wrap from the top of can to hold later.
Stuff sushi rice into the can, about 1-2cm thick (adjust to taste). Make the rice compact and remove by taking the cling wrap out, to keep the rice in shape.
Remove rice from cling wrap and place onto a span-sized nori sheet. Then place the spam onto the rice and wrap with a nori strip.
Repeat the steps for the rest and serve immediately.
Tip
Be creative and have different sizes of nori strips, or wrap it like sushi. Adjust your rice to spam ratio to your preference.
