Preheat oven to 350°F.
Wash and dry the lettuces. Set aside in a large bowl in the refrigerator.
Wash, halve and core the pear.
Melt the butter.
Toss walnut pieces with half the melted butter and a pinch of salt. Spread walnuts on a baking sheet and toast in the oven, just until they begin to turn golden, about 5-7 minutes. Watch them carefully, you don't want to burn them.
Stir the honey into the other half of the melted butter. Brush onto the cut side of the pears. Place on a baking sheet, sprinkle with a pinch of salt, and roast until pears start to take on some color, about 20-25 minutes, depending on your oven.
Let the nuts and the pears cool. Slice or cube the roasted pear.
Put the pears, goat cheese and walnuts in the bowl with the lettuce. Season lightly with salt and pepper. Drizzle on ¼ - ⅓ cup of dressing and toss gently but thoroughly. Serve.
