First, make the meatballs. Split the skins of the sausages and squeeze out the meat into a large mixing bowl.

Add the mince, onion, parsley, parmesan, breadcrumbs, eggs and lots of seasoning. Get your hands in and mix together really well – the more you squeeze and mash the mince, the more tender the meatballs will be.

Heat the oven to 220C/200C fan/gas 7. Roll the mince mixture into about 50 golf-ball-sized meatballs. Set aside any meatballs for freezing, allowing about five per portion, then spread the rest out in a large roasting tin – the meatballs will brown better if spaced out a bit.

Drizzle with a little oil (about 1 tsp per portion), shake to coat, then roast for 20-30 mins until browned.

Meanwhile, make the sauce. Heat the olive oil in a large saucepan. Add the garlic cloves and sizzle for 1 min.

Stir in the chopped tomatoes, red wine, if using, caster sugar, parsley and seasoning. Simmer for 15-20 mins until slightly thickened.

Stir in a few basil leaves, if using, spoon out any portions for freezing, then add the cooked meatballs to the pan to keep warm while you cook the spaghetti in a pan of boiling, salted water.
Spoon the sauce and meatballs over spaghetti, or stir them all together and serve with extra parmesan and a few basil leaves, if you like.
