Scrub the Japanese sweet potato and dice into small 1/2-inch cubes to ensure even cooking.
Heat the avocado oil in a large non-stick skillet over medium heat and add the diced potatoes and red onion.
Sauté for 8-10 minutes, stirring occasionally, until the potatoes are tender and have developed a golden-brown crust.
Add the ground turkey to the skillet, breaking it up with a spatula, and season with sea salt, black pepper, and garlic powder.
Cook until the turkey is fully browned and cooked through, then stir in the baby spinach until just wilted.
Pour the liquid egg whites over the hash mixture and stir constantly for 1-2 minutes until the whites are set and opaque.
In a separate small non-stick pan, fry the whole egg to your preference, ideally leaving the yolk slightly runny.
Transfer the hash to a plate, top with the fried egg, and drizzle with coconut aminos before serving.
