How to make Black lentil and harissa-roasted veggie bowl

  1. Preheat the oven to 220°C (200°C for fan).

  2. Bring a medium saucepan of salted water to a boil. Add the lentils and adjust the heat to simmer for 25–30 minutes, or until just cooked through. Drain the lentils and transfer them to a large bowl; allow to cool slightly.

  3. In a small bowl, whisk together the coriander, 3 tablespoons of oil, 1 tablespoon of harissa paste, 2 teaspoons of salt, and ½ teaspoon of pepper.

  4. Arrange the sweet potatoes and tomatoes on a rimmed baking tray. Drizzle with the harissa oil (reserve the bowl for later) and roast for 25–30 minutes, tossing once, until the sweet potatoes are tender and browned on some sides and the tomatoes burst.

  5. In the reserved bowl, whisk together the vinegar, honey, and the remaining 1 tablespoon of harissa. Gradually stream in the remaining 4 tablespoons of oil while whisking constantly until emulsified. Season the vinaigrette with salt.

  6. Add half of the vinaigrette to the lentils and toss to combine. Taste and adjust seasoning with salt and pepper as needed.

  7. Divide the lentils among bowls and top with the roasted vegetables and coriander. Drizzle with the remaining vinaigrette.

  8. Note: The lentils can be cooked up to 3 days in advance. Allow to cool, then cover and chill until needed.
