Beetroot and goat's cheese stacks

Choose 12 even-sized slices of beetroot, pat dry with paper towel, then lay in a shallow dish. Cover with the oil and balsamic, then set aside at room temperature for 1 hour.

Place the chives, milk and goat's cheese in a bowl. Season with sea salt and freshly ground black pepper, then mash with a fork until smooth.

Just before serving, drain the beetroot (reserving dressing) and pat slices dry with paper towel. Place 1 beetroot slice on a serving plate. Spoon the cheese mixture into a piping bag and pipe some onto the beetroot (alternatively, spread about 1 tbs of mixture over the beetroot with the back of a spoon). Repeat with more beetroot and cheese, then finish with a final beetroot slice. Repeat to make 4 stacks.

Garnish each stack with a few leaves, sprinkle some walnuts around each plate, then drizzle with the reserved dressing. Serve immediately.
