Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
In a large mixing bowl, whisk together the self-rising flour, egg white powder, garlic powder, and sea salt until well combined.
Add the non-fat Greek yogurt to the dry ingredients and stir with a spatula until a shaggy dough begins to form.
Turn the dough onto a lightly floured surface and knead gently for 1-2 minutes until smooth and elastic.
Divide the dough into 6 equal portions and roll each into a long rope, approximately 6 inches in length.
Place the dough ropes on the prepared baking sheet and brush the tops evenly with the whisked egg white.
In a small bowl, mix the minced fresh garlic, dried oregano, and extra virgin olive oil, then spoon this mixture over the breadsticks.
Sprinkle the grated parmesan cheese evenly over the top of each breadstick, pressing slightly so it adheres.
Bake for 12-15 minutes until the breadsticks are puffed and develop a beautiful golden brown exterior.
Allow to cool for 5 minutes before serving to ensure the center is perfectly set and chewy.
