Place lettuce, cranberries and walnuts on platter.
In a blender, puree pears and pear or grape juice till smooth. Add vinegar, olive oil, lemon juice, brown sugar or honey, salt and pepper. Blend. Turn off blender. Add chives and Gorgonzola give a quick whirl. You don’t want to blend more than a second or two because you want your Gorgonzola a little chunky and your chives will turn the dressing green if blended too long. Dress salad right before serving. Keep extra dressing in the fridge. Use within 24 hours.
