Heat your grill to high heat.
In a small bowl, combine the honey and balsamic vinegar.
While the grill is heating, prepare all the fixings (brie, arugula, and chopped candied nuts) on a dish or bake sheet to bring out to the grill with you.
Roll out the pizza dough and kinda, sorta shape it into a rectangle.
Bring everything out to the grill, including a pair of thongs. Transfer the rolled out dough onto the grill. Grill for 2 minutes or until slightly charred on the bottom. Flip the dough over, add the toppings: lay out cheese, arugula, and nuts. Cook another minute or two, covered, until bottom of crust is slightly charred and cheese is melted. Remove pizza from the grill and drizzle with the balsamic honey. Serves 4 as an appetizer.
