Preheat oven to 425°F and place pizza dough or crust on a lightly greased pizza pan or baking sheet.
Brush the crust edges with olive oil, then spread BBQ sauce evenly over the entire surface of the dough, leaving a small border for the crust.
Toss the shredded chicken with 2 tablespoons of additional BBQ sauce, then distribute evenly over the pizza.
Layer the sliced pears and red onion over the chicken, then top with both mozzarella and white cheddar cheeses.
Bake for 12-15 minutes until the crust is golden and cheese is melted and bubbly.
Remove from oven, sprinkle with fresh cilantro, slice and serve hot.
