Any kind of blue cheese (gorgonzola, etc.) can be substituted for the Rocquefort.
1 lb green beans
several strips of bacon
4 oz cheese
1 1/2 cups toasted walnut halves
Cook the beans. Cook the bacon separately and remove. Add the beans to the bacon fat for two minutes. Add cheese, toss for 30 seconds. Sprinkle with walnuts, pepper and the bacon bits.
