I use the Speedy Pizza Dough which I generally roll and put into a well oiled rectangular cooking tray leaving the edges slightly thicker to keep the filling from going off the edge. A basic pizza dough with yeast would be preferable but I never have the time!
On the base I spread 1 tin chopped tomatoes with some juice drained off and mashed well. Sprinkle with pepper, a little salt and origanum or/and basil.
Grate mozzarella cheese over the top or layer with thin slices.
Top with any of the following or mix according to taste:
Mushrooms lightly fried.
Garlic lightly fried.
Bottled mussels - minus the bottle!!
Italian salami sliced.
Ham & Pineapple.
Mushroom, onion, green pepper and chillies to taste.
Sprinkle over a little oil or preferably lightly spray oil. Bake at 220º C for about 25 minutes or until the cheese is melted and the dough is well risen.
