Step #1 Mix together the bread mix, tomatoes, half the oil, the rosemary, olives & water until it forms a firm dough.
Step #2 Turn out the dough onto a lightly floured surface & knead thoroughly for 5 mins; return the dough to the mixing bowl & cover with a piece of oiled cling film.
Step #3 Leave the dough to rise in a warm place until it has doubled in size (this will take about an hr); meanwhile, 220 C, lightly grease two baking sheets & pr-heat the oven to 425F F, gas mark 7.
Step #4 Turn out the risen dough, punch down & knead again; divide dough into two rounds, place on the baking sheets then punch hollows in the dough.
Step #5 Trickle over the remaining olive oil & sprinkle with salt, bake the focaccia for 12-15 mins until golden brown & cooked; slide off onto wire racks to cool, but eat when still slightly warm.
