1.Preheat oven to 220°C/200°C fan-forced. Line 2 baking trays with baking paper. Place capsicum, zucchini and onion on one prepared tray. Drizzle with 1 tablespoon oil. Bake for 15 minutes or until tender. Remove vegetables from tray. Discard paper. Line tray with a clean sheet of baking paper.
2.Meanwhile, place flour in a medium bowl. Add milk, 1 cup water and remaining oil. Using hands, mix to form a smooth dough. Divide dough in half. Roll each half into a 22cm round. Place on prepared trays.
3.Bake for 5 minutes or until light golden and puffed. Remove from oven. Top with pasta sauce, roasted vegetables, olives and cheeses. Bake for 10-15 minutes or until cheese melts and bases are golden. Serve at once with salad.
This dough will also make 1 large rectangular pizza. On a large, rectangular, baking paper-lined baking tray, roll out dough to 2cm thick. For a speedy option, use a jar of mixed antipasto or leftover roast vegetables.Note
