I made this up for my brother last night when he called with $10 in his hand at the supermarket ... It's great recipe for kids just starting out in the kitchen: cheap, easy, filling and it tastes good! It is worth buying the best sausages you can as they will provide the extra flavour.
If the spaghetti is ready before the sauce, drain it and pour over a good glug of olive oil … this will stop it sticking together.
I've done this with Italian fennel sausage meat - which actually happened when I realised I had no mince and found some of the sausages in the freezer. It tastes so much better than regular mince - the flavour is fantastic
