Place the shredded Russet potato in a clean kitchen towel and squeeze out all excess moisture to ensure maximum crispiness.
Heat a non-stick skillet over medium-high heat with half of the avocado oil.
Add the ground turkey and diced yellow onion to the skillet, seasoning with half of the sea salt, black pepper, garlic powder, and smoked paprika.
Cook the turkey until browned and cooked through, then remove from the pan and set aside.
Wipe the skillet clean, add the remaining oil, and press the shredded potatoes into two flat rounds.
Cook the potato rounds for 4-5 minutes per side until deeply golden and crispy.
In a separate small non-stick pan, scramble the liquid egg whites with the remaining seasonings until just set and fluffy.
Assemble the stacks by placing one hash brown round on a plate, topping with the turkey and egg whites, then placing the second hash brown round on top.
Finish the dish with a dollop of plain nonfat Greek yogurt and a sprinkle of chopped fresh chives.
