In a small pan, lightly toast the hazelnuts. Roll them around the pan while they toast. It should take no more than a minute until they are fragrant. Remove them from the heat and allow them to slightly cool. Roughly chop the hazelnuts and set aside.
In a wide rimmed bowl, combine the chopped arugula, arugula, chopped hazelnuts, and sliced Asian pear.
If desired, crumble goat cheese or gorgonzola cheese over the salad.
Sprinkle some flakey salt to taste.
Drizzle over balsamic vinegar and extra virgin olive oil and lightly toss the salad through to combine.
