Preheat your oven to 400°F and line a large baking sheet with parchment paper.
In a medium mixing bowl, combine the Greek yogurt, self-rising flour, and nutritional yeast, stirring until a thick dough begins to form.
Transfer the dough to a lightly floured surface and knead gently for 2 minutes until the texture is smooth and no longer sticky.
Divide the dough into small, uniform pieces and roll them between your palms to create bite-sized balls.
In a small ramekin, whisk together the egg white and water to create a light egg wash.
In a separate shallow bowl, mix the parmesan cheese, garlic powder, sea salt, black pepper, and dried parsley.
Brush each dough ball with the egg wash, roll it thoroughly in the parmesan-garlic mixture, and place it on the prepared baking sheet.
Lightly mist the bites with avocado oil and bake for 12-15 minutes until they are golden brown and slightly crisp on the outside.
