Peel and dice the sweet potato into small 1/2-inch cubes to ensure even cooking.
Heat the avocado oil in a large non-stick skillet over medium heat.
Add the diced sweet potatoes and onions to the skillet, cooking for 8-10 minutes until the potatoes are tender and slightly caramelized.
Slice the chicken sausage into rounds and add them to the skillet along with the diced red bell peppers.
Sauté for another 5 minutes until the sausage is browned and the peppers are soft.
Stir in the baby spinach, sea salt, black pepper, and smoked paprika, cooking just until the spinach begins to wilt.
Whisk the egg whites in a small bowl and pour them evenly over the vegetable and sausage mixture.
Create two small wells in the mixture and crack the whole eggs into them.
Cover the skillet with a lid and cook for 3-4 minutes, or until the egg whites are set and the yolks are cooked to your preference.
Serve immediately directly from the skillet for a hearty, high-protein start to the day.
