Serve this tasty salad in the autumn when new crop walnuts and apples are in their prime. The contrast of tastes and textures is what makes this salad successful: the salt of the bacon is mellowed by the sweet juiciness of the apple, and the mild pungency of the Stilton adds earthy creaminess.
Combine the vinaigrette ingredients in a glass jar and shake vigorously to combine.
Place the greens in a salad bowl and add half of the vinaigrette. Toss to coat the leaves, adding more dressing sparingly, as needed.
Divide the greens among 4 chilled salad plates and sprinkle each serving with some of the nuts, bacon, and cheese. Garnish with the apple slices and serve immediately.
