Chicken Salad with Walnuts and Roquefort Dressing

Ingredients

• 0.5 pound leaf lettuce green ()
• 0.5 teaspoon fresh-ground pepper black
• 6 tablespoons olive oil 
• 3 quarts radicchio thinly ( 1 pound in all)
• 0.3 pound roquefort blue crumbled
• 4 servings salt 
• 1 pound chicken breasts boneless skinless ( 3)
• 2 tablespoons cup heavy whipping cream sour
• 0.5 cup walnuts 
• 1.5 tablespoons white-wine vinegar 

Equipment

• bowl
• frying pan
• whisk

Directions

1. In a large frying pan, toast the walnuts over moderately low heat, stirring frequently, until golden brown, about 5 minutes.
2. Remove the nuts from the pan and chop them into fairly large pieces.
3. In the same pan, heat 1 tablespoon of the oil over moderate heat. Season the chicken breasts with 1/4 teaspoon each salt and pepper and add them to the pan. Cook the chicken until brown, about 5 minutes. Turn and cook until almost done, about 3 minutes longer. Cover the pan, remove from the heat, and let steam for 5 minutes.
4. Remove the chicken breasts from the pan. When they are cool enough to handle, cut the chicken breasts into bite-size pieces.
5. Meanwhile, in a glass or stainless-steel bowl, whisk together the vinegar, sour cream, 1/8 teaspoon salt, and the remaining 1/4 teaspoon pepper.
6. Add the remaining 5 tablespoons of oil slowly, whisking.
7. Add the Roquefort and stir just to combine, leaving the dressing chunky.
8. In a large glass or stainless-steel bowl, toss the lettuce and the radicchio with half the dressing.
9. Put the salad on plates. Top the salads with the chicken. Spoon the remaining dressing over the chicken and then sprinkle with the nuts.
10. Wine Recommendation: The salty Roquefort cries out for a sweet wine to provide contrast--but
11. Sauternes, Roquefort's classic cheese-course partner, is too sweet. Try instead a drier and much less expensive Cteaux du
12. Layon from the Loire Valley.
