Slice your potatoe(s) without peeling, and preheat the oven to gas mark 5/190°C (355°F)

Slice each steak into 8 pieces

At this stage you might want to brown off the pork and onions in a skillet

Line an oven proof dish with sliced onion

Add a layer of pork

Onions again...

...then a final layer of pork

Add the sweetcorn and peas

Finally, add a layer of parsnips and carrots

Add to the dish until it almost covers the vegetables, but not quite

Cover in tin foil and cook for 90 minutes

Finally, remove from the oven, and remove the foil. Add a layer of potatoes, drizzle with the olive oil or butter, then season.

Put in the oven for another hour (uncovered) or until the potatoes have browned

Serve as is, or with a pickled vegetable, like beetroot or red cabbage
