Is it a ‘cheat’ or is it a flan?
This is often called a “cheat’s” pizza but it could be seen as a ‘real’ vegetable flan. In fact it’s nearly a quiche.
What’s certainly true is this is a very useful method to make an infinite variety of easy going, fun and tasty meals. The principle is the same: roll-out the pastry, precook and top with anything you like. It could be made with grilled Mediterranean vegetables. Ham, bacon, sausages, or pepperoni can been included. A version with spinach, feta and mushrooms would be good. Or try tuna fish or prawns with tomatoes and roasted red peppers…
I would avoid putting too much liquid on the pastry as it will end up with a soggy bottom.
NB: The final heating will not thoroughly cook raw ingredients. Therefore give ingredients that need to be cooked – or would be better cooked – an initial separate cooking (as I have done for the courgettes, leeks, onions and roasted tomatoes in the above recipe).
