2 Onions, softened only, in olive oil with 3 cloves of finely sliced garlic added for the last few minutes. Careful not to burn. Remove from heat and set aside. Mince into a large saucepan, mine is stainless steel and I use it for the onions also) turn up the heat and again stirring constantly so as not to burn brown off the mince and when it is all browned and separated so as not to form lumps add half a tube of tomato puree, add the set aside onions and garlic, and for that much mince, 3 X 500 g boxes of passata. Stir and add a little water if too solid. I now add fresh oregano from the garden and fresh basil leaves from a plant that is in a pot on the kitchen window sill. Dried basil and oregano will suffice but is not as tasty. I also season the onions with salt and black pepper and the mince at the time of cooking them off, but carefully, it is hard to take salt out but easy to add a bit. Then simmer for at least an hour on a very low heat, covered to stop splashes, and stirred regularly.
