When the skillet is quite hot, add the tomatoes, skin down, crowding them in if necessary. Cook
for 1 to 2 minutes or until they are blistered, then stir in with the sausage. Cook for 2 more
minutes, until both tomatoes and sausage are slightly browned. Stir in gnocchi and cook just
until all is combined, but the tomatoes have not broken down into sauce.
