Mince the onion and microwave it in a heatproof container covered with plastic wrap for 1 minute at 600W. Let it cool.

Dice the processed cheese into 1cm cubes.

In a bowl, mix ground meat, onion, and filling ingredients until sticky. Divide into 6 portions and shape into flat, round patties.

Heat salad oil in a frying pan and cook the patties on medium heat until browned.

Flip the patties, cover with a lid, and cook on low heat for about 5 minutes.
