Pasta is already cooked in a large amount of salted boiling water, as it is written in the instructions on the package.
2 minutes before cooking, I throw the pasta in a colander, and let it drain, just 1 minute.
The paste should be harder than "Al dente".
Immediately mix with tomato sauce.
While the sauce is stewed and the pasta is cooked: I cut the leeks into small circles and fried them in vegetable oil.
Cherry cut it into quarters, and I found some big ones.
Cheese grated on a coarse grater.
When I cooked with mozzarella, I tore it into pieces with my hands.
