HOW TO DO IT

1. Heat the oil in a large frying pan, add the onions and fry over a medium heat for 3 mins, until softened. Turn the heat to high, add the garlic, mince and aubergine, and fry for 5 mins to brown. Add the purée, tomatoes, herbs and stock, bring to the boil and simmer for 25 mins, until the beef is tender. Add gravy granules to thicken, if you like.

2. Preheat oven to Gas 6/200°C. Meanwhile, cook the pasta in boiling water according to pack instructions, then drain and set aside. To make the white sauce, put the butter, flour and milk into a large jug. Microwave on high for 4 mins, stirring twice, until the sauce has boiled and thickened.

3. Stir the pasta into the meat mixture, then spoon into a baking dish. Pour the sauce over, sprinkle with the cheese and bake for 20 mins until golden.
