In a large bowl, combine 2 cups whole wheat flour, 1 cup plain Greek yogurt, and a pinch of salt. Mix until a dough forms and knead for about 5 minutes until smooth.
Heat a frying pan over medium heat and add 1 tablespoon olive oil. Cook 1 pound of diced chicken breast with salt and pepper until fully cooked. Set aside.
Preheat your oven to 475°F (245°C) and, if using, place a pizza stone inside.
Roll out the dough into a 12-inch circle on a floured surface and carefully place it on a pizza stone or lined baking sheet.
Spread a layer of tomato sauce over the dough, leaving a border for the crust.
Top with cooked chicken, 1 cup mozzarella, red onions, and bell pepper slices. Sprinkle with oregano.
Bake the pizza for 12-15 minutes until the crust is golden brown and cheese is melted.
Cool for a few moments, slice, and serve.
Notes
To keep your pizza fresh, store in an airtight container in the refrigerator, and reheat in an oven to retain the crust's crispness without drying it out.
