Preheat your oven to 400°F and line a large baking sheet with parchment paper.
In a medium mixing bowl, whisk together the white whole wheat flour, baking powder, garlic powder, and sea salt.
Add the Greek yogurt and 0.25 cup of the liquid egg whites to the dry mixture, stirring until a shaggy dough forms.
Turn the dough out onto a lightly floured surface and knead for approximately 2 minutes until smooth and elastic.
Roll the dough into a rectangle about 1/2 inch thick and use a knife to cut it into 8 even strips.
Twist each strip twice and place them on the prepared baking sheet, then brush the tops with the remaining 0.25 cup of liquid egg whites.
Bake for 12 to 14 minutes or until the breadsticks are puffed and turn a light golden brown.
While the breadsticks bake, whisk together the extra virgin olive oil, minced garlic, and dried parsley in a small bowl.
Remove the breadsticks from the oven and immediately brush them with the garlic oil mixture while they are still hot.
Sprinkle the parmesan cheese evenly over the breadsticks and serve warm.
