As we have just seen, this recipe is really very easy to make, but the funny thing is that it is also perfect when served in endless different versions: cold meats, cheeses, olives, spices, these puff pastry turnovers are also a great opportunity to make an fridge-emptying recipe with whatever you may have left over in the fridge. Instead of cooked ham, you can use any other cold meat, such as prosciutto , salami, speck and so on. If you want a creamier result, add some other cheese along with the Grana Padano, such as stracchino or some mild gorgonzola. All you have to do is add a small line of cheese on top of the ham; the oven will do the rest, melting the cheese and making your pastries tasty and springy. Or another idea is making them with some mozzarella, anchovies, a little tomato puree, some chopped fresh basil leaves and to finish it all off, a sprinkling of grated cheese.
