Remove stem and leaves from beetroot and quarter unpeeled beetroots. Toss beetroot in half the oil and place on a lined baking tray in a moderately hot oven, 190°C for 15 mins.
Toss sweet potato (kumara) in remaining oil, place on a baking tray with beetroot and continue to bake for a further 30 minutes or until vegetables are tender. When beetroot is cool enough to handle, peel.
Toss rocket, beetroot, sweet potato, macadamia nuts and feta together in a large bowl.
Combine dressing ingredients and drizzle through the salad.
Tips
Try adding other vegetables of your choice, such as baby spinach leaves, snow peas or even fresh or roasted capsicum, for a fresh new flavour.
