This is a perfect salad for Thanksgiving or Christmas,  inspired by Nigella Lawson (who had used chestnuts). It is festive, colourful, refreshing, and great to take to a party. 

The dressing can be made in advance. 

1 or 2 radicchio, torn into bite-size pieces

100g pecans

100g crumbly blue cheese, such as Dorset Blue Vinny

For the dressing:

2 tsp fresh lime juice

2 tsp fresh orange juice

1 tsp grain mustsrd

1 tsp honey

1 tbsp olive oil

1 tsp toasted sesame oil

Pinch of salt

Put all the dressing ingredients in a jar, close and shake to mix. Taste.

To assemble, carefully toss the radicchio and nuts in a salad bowl with sufficient dressing. Add most of the cheese and toss again. Sprinkle the remaining cheese over the top.
