Ingredients:
500g baby Red Royale potatoes*, quartered
600g Coles Australian No Added Hormones Beef Rump Steaks
2 tablespoons pistachio dukkah
2 tablespoons olive oil
1 leek, pale section only, thinly sliced
2 garlic cloves, crushed
1 cup finely shredded green cabbage
1/2 cup (120g) sour cream
1 tablespoon thyme leaves
Steamed baby broccoli, to serve

Method:
Cook the potato in a medium saucepan of boiling water for 15-20 mins or until tender. Drain and return to the pan.
Meanwhile, heat a greased barbecue grill or chargrill on medium. Sprinkle the beef with the dukkah and gently press to coat. Cook the beef on the grill for 2-3 mins each side or until cooked to your liking. Transfer to a plate and cover with foil. Set aside for 5 mins to rest. Thickly slice.
While the potato is cooking, heat oil in a large non-stick frying pan. Cook leek, stirring, for 2-3 mins or until leek softens. Add garlic and cabbage. Cook for 2-3 mins or until cabbage wilts.
Use a potato masher or fork to mash potato until almost smooth. Stir in sour cream and leek mixture. Top with thyme. Serve with beef and baby broccoli.
