Cooking Steps

1

Boil the kettle. Bring a large saucepan of water to the boil. Peel and cut the kumara into 2cm chunks. Add the kumara to the saucepan of boiling water and cook until easily pierced with a knife, 10-15 minutes. Drain and return the kumara to the saucepan. Add the butter and salt and mash using a potato masher or fork until smooth. Cover with a lid to keep warm.

2

While the kumara is cooking, pick the mint leaves and finely chop. In a medium bowl, combine the mint, sugar, boiling water and a pinch of salt. Stir to combine, then set aside to cool. When the sauce has cooled, stir in the white wine vinegar and set aside.

3

Slice the zucchini into 1cm half-moons. Trim the green beans. Roughly chop the silverbeet. Finely chop the garlic (or use a garlic press).

4

In a large frying pan, heat a drizzle of olive oil over a medium-high heat. Season the lamb leg steaks on both sides with salt and pepper. When the pan is very hot, add the lamb and cook for 2 minutes on each side for medium-rare (depending on thickness), or 3 minutes for well done. Transfer to a plate, cover with foil and set aside to rest for 5 minutes.

5

Return the frying pan to a high heat with a drizzle of olive oil. Add the zucchini and green beans and cook until tender, 3-4 minutes. TIP: Add a splash of water to help the veggies cook evenly. Add the silverbeet and garlic and cook until wilted and fragrant, 2 minutes. Season to taste with salt and pepper.

6

Thinly slice the lamb. Divide the kumara mash and garlic veggies between plates. Top with the lamb and spoon over the mint sauce.
