Heat the avocado oil in a medium non-stick skillet over medium-high heat.
Add the ground turkey, sea salt, black pepper, garlic powder, and smoked paprika, breaking the meat apart with a spatula until browned and cooked through.
Toss in the diced red bell pepper and yellow onion, sautéing for 3 to 4 minutes until the vegetables are tender-crisp and fragrant.
Stir in the baby spinach and cook for 1 minute until just wilted.
Lower the heat to medium and use a spoon to create two small wells in the turkey and vegetable mixture.
Pour the liquid egg whites evenly across the skillet, then crack one whole egg into each of the two wells.
Cover the skillet with a lid and cook for 3 to 5 minutes, or until the egg whites are set and the yolks are cooked to your preference.
Remove from heat, sprinkle with crumbled feta cheese, and serve immediately directly from the skillet.
