Blanch 2 slices of spam in boiling water to reduce saltiness and grease.

Cut the spam into bite-sized pieces and pan-fry until golden.

Slice 1 onion thinly and sauté with 1 tbsp minced garlic until slightly softened.

Add 2 tbsp soy sauce, 1 tbsp sugar, 2 tbsp mirin, and 6 tbsp water to the pan. Simmer on low heat.

Once the onion becomes tender, add the fried spam and simmer briefly.

Beat 1 egg and pour it over the mixture. Add chopped green onion and cook until the egg is slightly runny.
