Preheat the oven to 220C. Divide the dough into eight pieces and roll out each one on a lightly floured surface to a small oval about 5mm/1/4 in thick.

Place well apart on two greased baking sheets and prick with a fork. Brush the bases well with 15ml/1 tbsp of the garlic oil.

Halve, then slice the onions into thin wedges. Scatter over the pizza bases. Remove the rind from the Gorgonzola. Cut the cheese into small cubes, then scatter it over the onions.

Cut the garlic lengthways into thin strips and sprinkle over, along with the sage. Drizzle the remaining oil on top and grind over plenty of pepper.
