Method:
Ingredient option: You may substitute store-bought candied pecans for a simpler preparation.
Preheat oven to 325°F.
Spoon sugar and cinnamon into a large bowl or plastic bag. Mix well and set aside. Place egg white in a separate bowl, whisk until frothy, and add pecans. Toss to coat completely. Add pecans to cinnamon-sugar and toss well to coat all pecans. Spread them on a baking sheet and bake for 20 minutes. Remove from oven and allow them to cool, breaking them up with a spatula.
Meanwhile, toss pears, apples, greens, onion slices and cheese in a large serving bowl. Add pecans when cooled.
In a smaller bowl, whisk together the olive oil, vinegar, salt and pepper. Drizzle over salad, toss to combine and serve immediately.
