Preheat oven to 360°F (180°C) and line a baking sheet with parchment paper.
Remove any liquid on top of the Greek yogurt, if any is present.
In a large bowl combine whole-wheat flour with baking powder and Greek yogurt. Quickly stir until it comes to form a dough – adjust with more flour if it is sticky or a bit of Greek yogurt if it is too dry.
Transfer the mixture over a clean floured surface and knead to form a soft dough ball.
With the aid of a rolling pin and your hands, shape into a round of about 6-inch (15 cm), with the edges thicker than the center. Sprinkle more flour if it gets sticky.
Spread the pizza sauce over the crust, leaving a slight border around the edges. Sprinkle with shredded chicken (or your favorite toppings) and shredded mozzarella cheese.
Bake in hot oven for 15 to 20 minutes, or until the cheese has melted and the pizza crust is golden brown. Let cool for 5-10 minutes before serving.
