Spread the tortillas with pizza sauce and distribute the cheese and the fresh tomatoes over the bases.
Bake them in a preheated oven at 200°C conventional (top and bottom heat), or 180°C fan, for about 12-14 minutes. If you are baking 2 trays at a time, you will of course need to use the fan setting – and I would also recommend swapping the trays around once the pizzas are a little over halfway through baking.The tortilla pizzas should be golden and crisp at the edges.
Let the tortilla pizzas rest for a moment, then top them with pesto and fresh basil. Season with freshly ground pepper and a little dried basil, if you like.
