Make your béchamel.
Roll out your egg pasta so as to form a very very thin rectangle (1mm and 50×30).
Put it on the baking paper or on a cloth that it helps you to roll up your cylinder.
Lay over the béchamel, Stracchino in pieces and mozzarella, cooked ham, Parmesan, salt.
Fold the edges, seal everything with a brush of water.
Freeze for at least half an hour.
(I recommend it to cut nests better!)
Preheated your oven, oil a baking dish and make a base of béchamel.
Take your dough roll from the freezer and slice it.
Place your nests on the béchamel, add tomato, Parmesan, basil.
A knob of butter and oil as well.
Bake at 180 degrees for 30 minutes.
