Step 1

Squeeze the meat out of the sausages into a bowl (discard the skins) and combine with the mixed herbs and breadcrumbs. Shape into 8 equal-size balls, place on a plate, then put in the freezer for 5 minutes.

Step 2

Preheat the grill to medium-high. Cook the spaghetti according to the packet instructions, then drain. Meanwhile, heat the oil in a large frying pan and cook the onion for about 5 minutes. Add the meatballs and cook for a further 5 minutes, turning frequently, until browned. Stir in the tomato sauce and basil, then simmer for 10 minutes.

Step 3

Tip the cooked spaghetti into a baking dish, then add the meatballs and sauce. Sprinkle over the feta, then grill for 5 minutes. Serve scattered with the reserved basil leaves.
