PREPARATION: Preheat the oven to 230░C (450░F). Drain, deseed and chop the tomatoes. Wipe the mushrooms and slice evenly.
Press the dough out into a large round on an oiled baking tray. Spread with the tomatoes, season with salt and pepper and sprinkle with a little oil.
Divide the pizza into 4 equal parts, using the back of the knife to prevent cutting through the dough. Top one section with slices of mozzarella cheese, the second with chopped artichokes, the third with mushrooms and the last with drained, chopped tuna and slivers of garlic. Put in hot oven for 20 minutes.
PREPRATION TIME: 35 minutes
