Dice the sweet potato into small half-inch cubes to ensure even cooking.
Heat the extra virgin olive oil in a large non-stick skillet over medium heat.
Add the sweet potatoes to the skillet and cook for 8-10 minutes, stirring occasionally, until tender and slightly browned.
Slice the chicken sausage into rounds and add them to the skillet along with the diced bell peppers and red onions.
Sauté the mixture for an additional 5 minutes until the sausage is browned and the vegetables are soft.
Sprinkle the sea salt, black pepper, and smoked paprika over the ingredients and stir to combine.
Pour the egg whites evenly over the skillet mixture and stir gently until they begin to set and turn opaque.
Use a spoon to create a small well in the center of the skillet and crack the whole egg into it.
Cover the skillet with a lid and cook for 2-3 minutes until the whole egg white is set but the yolk remains runny.
Remove from heat, top with sliced avocado, and serve immediately.
