This vibrant vegan side dish celebrates the natural sweetness and earthy flavours of root vegetables. By combining classic red or white potatoes with two varieties of sweet potato, you create a beautiful contrast in textures and colours that looks stunning on the dinner table. The addition of fresh sage leaves is the secret to this recipe; as they roast in the olive oil, they become crisp and infuse the vegetables with a sophisticated, savoury aroma.
