Preheat your oven to 425°F (220°C).
Roll out the pre-made pizza crust on a floured surface.
Transfer the crust onto a baking sheet or pizza stone.
In a bowl, mix shredded chicken with BBQ sauce until well coated.
Spread a thin layer of BBQ sauce over the pizza crust.
Evenly distribute the BBQ chicken over the sauce.
Sprinkle shredded mozzarella cheese over the chicken.
Add sliced red onion on top of the cheese.
Drizzle a little olive oil and sprinkle garlic powder over everything.
Bake in the preheated oven for 15-20 minutes until the crust is golden and cheese is bubbly.
Remove from the oven and let cool for a few minutes.
Garnish with chopped cilantro and sliced green onions before slicing and serving.
