Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Add the ground turkey to the skillet, breaking it into small crumbles with a spatula until browned and fully cooked.
Stir in the diced yellow onion and bell peppers, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Add the shredded potatoes to the skillet, spreading them in an even layer and pressing down firmly with the spatula.
Season the mixture evenly with sea salt, black pepper, garlic powder, and smoked paprika.
Cook undisturbed for 5-6 minutes until the bottom is deeply golden and crispy, then flip carefully and cook for another 4 minutes.
Create a small well in the center of the hash brown mixture and crack the egg into it.
Cover the skillet with a lid for 2-3 minutes until the egg white is set but the yolk remains runny.
Sprinkle the nutritional yeast over the entire skillet and serve immediately while hot.
