If you feel like taking a shortcut here by using ready-cooked beetroot feel free, but roasting it yourself produces lots more flavour and is worth the time and effort.
Ingredients
4 medium beetroot (beets), about 450g (1lb), scrubbed and trimmed
Heat the oven to 180°C (350°F/Gas 4). Put the beetroots on a large piece of foil, drizzle with 2tablespoons of the olive oil and season with salt and pepper. Add the thyme and close the foil
