Stilton & Pear Salad Recipe

In a small bowl whisk together the vinegar, mustard, salt and pepper to taste. Add oil in a stream, whisking, and whisk the dressing until it is emulsified. In a bowl, toss the lettuce with half the dressing and divide salad among 4 plates. Halve and core the pear and cut it lengthwise into 1/4 inch slices. Arrange 1/4 pear slices decoratively on each plate, divide the Stilton and pecans among the salads and drizzle remaining dressing on top
