An all in one dish, I absolutely adore parsnips.
Heat the oven to 220 ̊C, fan 200 ̊C, gas 7. Toss the parsnips with the honey, 1 teaspoon of mustard, 1⁄2 tablespoon of oil and some seasoning. Spread out in a large shallow roasting tin. Add the sausages, pricking each a couple of times with a fork. Roast for 20 minutes, turning halfway.
Meanwhile whisk together the remaining olive oil, mustard and vinegar to make a tangy dressing. Season to taste
Tip the lentils and then the kale into the roasting tin. Sprinkle over 2 tablespoons of water then return to the oven for a further 3-4 minutes until the kale has wilted and the lentils are heated through. Pour in the dressing then mix everything together to serve
