Cauliflower, Grape, and Cheddar Salad

1 large head cauliflower broken into bite sized florets
6 tablespoons sunflower or other light oil
2 tablespoons sherry vinegar
1 teaspoon dijon mustard
1/2 teaspoon honey
1/4 cup raisins
1/3 cup hazelnuts, toasted and roughly crushed
2/3 cup seedless red grapes, halved
3 oz aged Cheddar cheese, coarsely crumbled
2/3 cup flat leaf parsley leaves, coarsely chopped
salt and black pepper

Preheat oven to 425.

Toss the cauliflower florets with half of the oil, 1/2 teaspoon salt and some freshly ground black pepper. Spread out on a baking sheet and roast for 20-30 minutes, stirring once or twice, until golden brown. Remove from the oven and set aside to cool.

To make the dressing, whisk together the remaining 3 tablespoons oil with the vinegar, mustard, honey and 1/4 teaspoon salt. Add the raisins and let them marinade for at least 10 minutes.

Just before serving, transfer the cauliflower to a large bowl and add the hazelnuts, grapes, Cheddar and parsley. Pour the raisins and dressing over the top, toss together, transfer to a large platter, and serve.
