I'll stick my oar in on this one.
I just use mince, Tomatoes, Onion, Basil and Garlic. Maybe a little chilli of some kind to add flavour.
I cook off the mince and chopped onions, add the tinned tomatoes and stick in a couple of crushed garlic cloves and a clove of chopped garlic. Let it reduce down and add the basil, add salt and pepper to taste if you really want to. Spot on.
Paddy.
