Preheat your oven to 400°F (200°C).
Place the sprouted grain tortilla on a parchment-lined baking sheet and toast for 3 minutes per side until it becomes slightly firm and crisp.
In a small mixing bowl, combine 4.5 oz of cooked and shredded chicken breast with the buffalo sauce until the meat is thoroughly coated.
Spread the buffalo chicken evenly across the surface of the toasted tortilla base.
Top the chicken with the shredded mozzarella cheese, diced red onion, and thinly sliced celery.
Bake the pizza for 7 to 9 minutes, or until the cheese is bubbly and the edges of the tortilla are golden brown.
While the pizza bakes, whisk together the Greek yogurt, dried dill, garlic powder, onion powder, sea salt, black pepper, and water in a small bowl to create a smooth ranch drizzle.
Remove the pizza from the oven and finish with a generous drizzle of the yogurt ranch before slicing into wedges.
