Start by chopping the onion, the garlic and the scallion. Also chop the tomatoes and the basil. I used cherry tomatoes and then you need a few more.
Remove the skin from the sausage.
Cut in small pieces.
Heat the olive oil in a pan. Add the salsiccia, and the chopped onions.
Allow to boil a couple of minutes.
Add the tomatoes...
....and the basil. Put on a lid and boil for about 15 minutes.
The sauce is ready!
Serve with pappardelle, black pepper and parmesan. Either serve the sauce on top or mix it with the pasta.
