Spray grill grate with cooking spray. Preheat grill to 425 degrees.
If using pizza dough, roll into a thin crust - ¼ inch thick. Place crust onto oiled grate. Grill for 3-5 minutes until set. Remove from grill.
Spread pesto sauce over baked side of the pizza crust. Top with tomato slices, chicken, artichokes and olives.
Sprinkle with cheeses. Grill for an additional 10 minutes, or until crust is baked and cheese is melted.
