In large frying pan, cook chicken in olive oil over medium-high heat until just cooked, 5-6 minutes; do not overcook.
Refrigerate until chilled. Once chilled, coat chicken with barbecue sauce; set aside in the refrigerator.
Place dough onto pizza pan. Spread barbecue sauce evenly over dough.
Sprinkle smoked Gouda cheese over sauce. Cover with 3/4 cup shredded mozzarella. Distribute chicken pieces evenly over cheese.
Add red onion and sprinkle an additional 1/4 cup mozzarella over top.
Bake at 400 degrees until crust is crisp and golden and cheese at center is bubbly, 8 to 10 minutes.
Remove from oven and sprinkle with 1 tablespoon cilantro.
