This is a really easy pasta sauce recipe - vary the flavour by adding different ingredients (see Top recipe tip below).
3 tbsp extra virgin olive oil
1 large onion, chopped
2 garlic cloves, crushed
3 x 400g cans of chopped tomatoes
¼ - ½ tsp dried chilli flakes
2 tsp balsamic vinegar
2 tsp sugar
1 large handful basil leaves, torn into small pieces
Salt and freshly ground black pepper
Grated parmesan cheese, to serve (optional)
Heat the oil in a saucepan and gently cook the onion and garlic until softened. Stir in the tomatoes, chilli flakes, balsamic vinegar and sugar. Bring to a simmer and cook slowly for 45 minutes-1 hour. Stir in the basil and season with salt and pepper. This can be left chunky or blended in a food processor for a smooth sauce.
Serve spooned over cooked pasta with plenty of parmesan cheese.
