To toast hazelnuts, heat oven to 350°F. Spread nuts in ungreased shallow pan. Bake uncovered 6 to 10 minutes, stirring occasionally, until light brown. Rub nuts in a kitchen towel to remove loose skins (some skins may not come off).
To drizzle the melted white chips over the pizza, pour melted mixture into a resealable food-storage plastic bag, cut off a small tip from a corner of the bag, and squeeze bag to drizzle.
