Buttermilk and low-fat yogurt replace some of the mayonnaise and the usual sour cream for a lighter, more refreshing dressing. This is a favorite for spooning over chilled wedges of iceberg lettuce, and it also goes well with hearty Belgian endive spears. The dressing can be made with any crumbly blue cheese, ranging from mild Danish blue to the more pungent Roquefort, Stilton, or Gorgonzola.

Ingredients

　　Whisk together 1 cup buttermilk, 1/4 cup each mayonnaise and plain low-fat yogurt, 1 tablespoon fresh lemon juice, and 1/2 teaspoon coarsely chopped fresh thyme in a bowl to combine, then stir in 4 ounces crumbled blue cheese and season with coarse salt and freshly ground pepper.
