Chop 60g of green onion into small 2–3mm pieces.

Dice 30g butter and 1 slice of cheddar cheese finely.

In a bowl, combine green onion, butter, cheddar cheese, sugar, and 60g garlic aioli sauce. Optionally, add a pinch of parsley.

Cut the top of each bread roll into a 9-square grid pattern.

Fill the cuts with the prepared sauce mixture.
