Leek & Caerphilly crumble tart
Use Caerphilly or Wensleydale cheese and a nutty topping in this make-ahead, lunchtime tart
Heat oven to 200C/180C fan/gas 6. Peel the beetroot and cut each into 8 wedges. Cut the onions and butternut squash into roughly the same size. Spread out in a large roasting tin. Mix the vinegar and sugar until dissolved, then whisk in the oil. Pour over the vegetables, toss and roast for 40-45 mins until charred and soft, stirring halfway through cooking.
To make the horseradish cream, mix together the soured cream, horseradish, lemon juice and some seasoning.
To serve, put the roasted veg in a large bowl or on a platter, followed by the watercress, then drizzle over the horseradish cream. Serve warm or cold.
