Preheat your oven to 180ºC.

Slice the tops off the heads of garlic, exposing the cloves. Drizzle with olive oil and sprinkle with half a teaspoon of salt. Wrap each head in aluminium foil and roast for 30 minutes. Set aside to cool. Flip your oven over to the grill setting.

In a bowl, combined softened butter with roast garlic cloves squeezed out of their skins, parsley, oregano, cheese, remaining salt and pepper and mix together to make a rough paste.

Place sliced rolls on a baking tray and spread generously with the cheesy garlic butter. Grill for 5-6 minutes until golden and serve immediately.
