At the back of the fridge..."What do you mean 'there's nothing in the fridge'?"
For a surprisingly scrummy lunch take 1 tortilla/wrap/flat bread thingy, spread with Greek Yoghurt (or white sauce) and then top with whatever sliced veggies you like. Mushrooms, leeks, onions, spinach, peas all work well. Add some fresh herbs, salt & pepper, grated cheese and a little ground nutmeg. If you've got any cooked or cured meat dice that up and sprinkle that over too.
Pop in the oven until the cheese has melted and the 'pizza' starts to get a little singed at the edges.
I made the one in the picture with a leek which was going a bit bendy, mushrooms which were getting rather wrinkly and a stub of old cheese which wasn't much use for anything else and honestly it was bloody good. The nutmeg brings the white sauce-onion-cheese combo together and really reminds me of Flammkuchen which is served at festivals and street parties in Germany.
