Peel and halve the pears, cut out the core and cut the pear halves into a fan shape. Put them on a baking tray and crumble the Roquefort cheese over them. Bake under the hot grill of the oven (or at highest temperature).
Clean and wash the salad. Peel and finely dice the shallot and mix with vinegar, salt and pepper. Whip the oil into it. Pour marinade over the salad. Divide the salad between four plates. Arrange pear fans on top.
Quarter bacon slices and fry them in a pan without fat until crispy. Pour over the pears and serve.
