Roast Beetroot and Carrot Lentils With Black Cabbage

Serves: 4
Takes: 35 mins

This is an incredibly simple and filling salad. It is designed to be served warm, but works just as well cold. If you want to make it more substantial - toss the vegetables with 5 tablespoons of pumpkin seeds.

When To Eat

We recommend eating this recipe from late August to the beginning of March. The main crop beetroot in the UK comes in during the summer months, but because of their ease of storage they can be enjoyed into the winter.

  • Thickly slice the beetroot and carrot, around a 1 cm thick. Zest and juice the lemon. Place the beetroot and carrots on an oven tray and cover with the olive oil, salt, cumin and half the juice of lemon. Mix well to incorporate the ingredients. Place in a 200˚c oven for 30 minutes. Or until the vegetables are starting to crisp.
  • Whilst the vegetables are cooking, prepare the lentils. Place in a pan, cover with water, and bring to a boil. Turn down to a simmer and cook for around 20 minutes, or until the lentils are cooked with a little bite. Don’t be tempted to overdo them - you’ll end up with a mushy salad.
  • When the roasted vegetables are done, remove from the oven. Drain the lentils and pour the cooked lentils into the oven tray. Mix well to combine. Return the tray to the oven for a further 5 minutes.
  • Roughly slice the cabbage and steam for 3-5 minutes until just tender. Then remove the roast veg from the oven. Add the cabbage and lemon zest to the tray. Toss to achieve an even spread of the cabbage and zest.
  • Drizzle the rest of the lemon juice on top if desired. Serve immediately.
