I'd forgotten about the Jamie Oliver ads and I was gonna suggest turkey meatballs rather than beef ones with a homemade tomato sauce and either spaghetti or pasta twirls. For the meatballs grate an onion into a bowl, add sprinkling of oregano & basil and a pinch of salt and pepper. Mix in the turkey mince (you can always bulk it out with some homemade breadcrumbs too) Make the mixture into small meatballs and dry fry in batches in a frypan so the outsides are browned. For the tomato sauce finely chop an onion, a clove of garlic and gently fry in a little olive oil. Add a couple of tins of tomatoes, a grated carrot (optional but it gives the sauce a sweet taste), a sprinkling of basil or oregano or both. Add a splash of red wine vinegar and a tsp of sugar. Bring to boil and as each batch of the meatballs is browned add them to the sauce mixture. When all the meatballs are browned, make sure the sauce is simmering, then turn the whole lot into the slow cooker and leaver in there for the rest of the day so the meatballs cook through. Then when you get home alls you've got to do is cook the pasta

If I'm feeling flush, I sometimes break up a ball of mozzerella cheese and add it to the mix in the slow cooker
