Remove excess oil from 200g spam using a paper towel, or blanch it briefly in boiling water.

Cut the spam vertically, leaving about 1cm at the bottom intact.

Quarter 3 slices of cheese and insert them into the cuts in the spam.

Preheat the air fryer to 180°C and cook the spam for 10 minutes.

Prepare the sauce by mixing 3 tbsp mayonnaise, 1 tsp sugar, 1 tbsp chopped green onion, and a pinch of pepper.
