Peel and dice the sweet potato into small 1/2-inch cubes to ensure they cook quickly and evenly.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the ground turkey and diced sweet potatoes to the skillet, breaking the turkey apart with a spatula.
Season the mixture with sea salt, black pepper, garlic powder, and smoked paprika.
Cook for 8-10 minutes, stirring occasionally, until the turkey is browned and the sweet potatoes are fork-tender.
Stir in the diced red bell pepper and yellow onion, sautéing for another 3-4 minutes until the vegetables soften.
Lower the heat to medium and pour the egg whites evenly over the turkey and vegetable mixture.
Gently fold the ingredients together until the egg whites are fully cooked and opaque.
Add the fresh baby spinach to the skillet and stir for 1 minute until just wilted.
Remove from heat and serve immediately while hot and steaming.
