Dice the sweet potato into small 1/2-inch cubes and finely chop the kale, red bell pepper, and onion.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the sweet potato cubes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and slightly browned.
Slice the chicken sausage into rounds and add them to the skillet along with the diced bell pepper and onion.
Sauté the mixture for another 5 minutes until the sausage is browned and the vegetables are soft.
Stir in the chopped kale and cook for 1-2 minutes until it is wilted and bright green.
In a small bowl, whisk together the eggs, egg whites, sea salt, black pepper, and garlic powder.
Reduce the heat to medium and pour the egg mixture over the ingredients in the skillet.
Gently fold and stir the eggs with a spatula until they are just set and fluffy, then serve immediately.
