Combine flour, yeast and sugar in a large bowl. Combine warm water with 2 tsp of the oil. Stir into flour mixture until just combined. Turn onto a lightly floured surface and bring dough into a ball. Knead for 3-5 mins, until dough is smooth and elastic. Place dough into a lightly oiled bowl, turning to coat with the oil. Cover with plastic wrap and a tea towel. Set aside in a warm place 1 hr until dough has doubled in size.

Preheat oven to 220°C or 200°C fan. Line a baking tray with baking paper. Roll dough to a 20 cm x 30 cm rectangle.

Sprinkle 1 cup of cheese and 2 tbsp of bacon over the dough. Starting from long edge, gold a third of the dough over and then over again. Flatten slightly and place on prepared tray. Brush with remaining oil. Scatter over remaining cheese and bacon. Bake for 15-20 mins, or until focaccia is crisp and golden.

Slice focaccia and serve warm
