Carbonara sauce for pizza

Poach an onion with a little oil and water.

When the onion is ready, add 200 ml of evaporated milk and a touch of ground pepper.

When it starts to boil add 40 gr of grana padano, you can put less or more cheese to taste, a little movement and ready.

As it is made very quickly, I recommend to make it and put it directly on the dough, as it thickens due to the cheese.

Then add the ingredients, I add cooked ham and mushrooms.
