Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a medium mixing bowl, combine the non-fat Greek yogurt, white whole wheat flour, baking powder, and sea salt.
Stir until a shaggy dough forms, then transfer to a lightly floured surface and knead for 1-2 minutes until smooth.
Divide the dough into 4 equal portions and roll each portion into a rope approximately 6 inches long.
Place the dough ropes onto the prepared baking sheet, leaving space between each.
In a small bowl, whisk the egg white until frothy and brush it generously over the tops and sides of each breadstick.
Evenly sprinkle the garlic powder, dried oregano, and grated parmesan cheese over the egg-washed dough.
Melt the ghee and lightly drizzle it over the breadsticks to ensure a golden, crispy finish.
Bake for 12-15 minutes, or until the breadsticks are puffed and the cheese has turned a deep golden brown.
