Gather the ingredients for your breakfast pizza puff pastry.
Thaw the puff pastry sheet to room temperature.
Preheat the oven to 425°F and line a baking sheet with parchment paper.
Heat a skillet over medium heat for the chicken.
Sprinkle a bit of flour on the puff pastry sheet and roll it out until flat like a pizza crust, trimming to your preferred size if needed.
Using the tip of a knife, score a shallow border about 1/2 inch from the edge of the puff pastry sheet, being careful not to cut all the way through.
Prick holes all over the puff pastry sheet with a fork.
Prepare the egg wash by scrambling the egg. Use a pastry brush to lightly coat the puff pastry sheet with egg wash.
Place the puff pastry sheet on the prepared baking sheet and bake for 10 minutes, or until golden brown.
While the puff pastry bakes, add oil to the hot skillet.
Cook the chicken breast for 5 to 7 minutes per side, keeping the skillet covered.
Allow the chicken to cool, then chop it into cubes.
Spread the BBQ sauce evenly over the puff pastry sheet.
Add the toppings by layering the cheese, chicken, turkey bacon, and onions over the BBQ sauce.
Bake the BBQ chicken puff pastry pizza for 20 minutes.
Garnish with chopped green onions and cilantro. Let cool for a few minutes before cutting and serving.
