Grate cheese. Wash thyme, shake dry, pluck leaves from the stalks. First cut the bread 3 times deep lengthwise, then cut 5-6 times crosswise, depending on length. Carefully break open the breads slightly so that they do not fall apart at the bottom.
Distribute the salami and cheese evenly into the cuts. Pour butter as flakes over the breads. Sprinkle with thyme.
Place on a baking tray lined with baking paper and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 8 minutes. Remove from the oven and arrange.
