Roast Beetroots and Sweet Potatoes

Preheat oven to 200 C / Gas 6.

In a bowl, toss the beetroots with 1/2 tablespoon olive oil to coat. Spread in a single layer on a baking tray.

Mix the remaining 2 tablespoons olive oil, garlic granules, salt, pepper and sugar in a large resealable plastic bag. Place the sweet potatoes and onion in the bag. Seal bag and shake to coat vegetables with the oil mixture.

Roast beetroots 15 minutes in the preheated oven. Mix sweet potato mixture with the beetroots on the baking tray. Continue baking 45 minutes, stirring after 20 minutes, until all vegetables are tender.
