Wash the lamb`s lettuce, remove the roots and place in a bowl. Wash the pears, quarter them lengthways, remove the core and stem and cut the quarters into small pieces and add to the lamb`s lettuce. Crumble the gorgonzola in small pieces into the bowl.
For the dressing:
Chop the onion finely. Whisk the oil and balsamic vinegar in a key. Stir in the cranberries and onions and pour the dressing over the salad.
The salad can be seasoned with freshly ground pepper to taste.
