parma ham salad with blue cheese and nutty honey dressing

Peel the grapefruits and segment, making sure that all the pith is removed. (Hold over a bowl to catch any juices that might escape. You will need about 3 tablespoons of juice to add to the dressing). Make the dressing by whisking the walnut and olive oil together with the honey and grapefruit juice. Season to taste. Peel, stone and slice the avocado. Toss the leaves, grapefruit segments, walnut halves and avocado slices with half the dressing and the place on to 4 serving plates or bowls. Divide the ham and cheese between the 4 plates. Drizzle over the remaining dress and serve immediately.
