Step 1 Start by cooking the potato in a pan of salted water for 20-25 mins until the potato is tender. Drain and mash the potato with the butter.

Step 2 Heat the olive oil in a heavy based pan over a medium heat. Add the bacon and cook until golden, approximately 5 mins.

Step 3 Add the spring onions and garlic and cook for 3 mins before adding the chard and continuing to cook for 2 mins.

Step 4 Finally stir through the mash and cheese and continue to cook until the bottom forms a nice crust, approx. 10 mins, stirring to break up the crust every 2-3 mins.

Step 5 Serve immediately.
