Gently fry the onions until translucent, add the mince and gently fry until brown. Add the beans, tomatoes, oxo's, tom puree, S&P, and the gravy granules and simmer until it has thickened a little, add the water if hardly any gravy.
Transfer to a lidded oven proof dish and layer the thinly sliced potatoes on top
Bake in oven on mark 5. or 375.f for about an hour or more, until potatoes are cooked, (I usually stick a blunt knife in the middle to check)Sprinkle the grated cheddar cheese on top and put back in oven (without the lid) till nice and golden
Serve with anything you want or on its own
Can either use corned beef or the left overs from the beef joint instead of mince. If using corned beef omit the salt.
