Slice the chicken sausage into 1/4-inch rounds and finely dice the red onion.
In a medium bowl, whisk together the whole eggs, egg whites, sea salt, black pepper, and garlic powder until well combined.
Heat the ghee in a large non-stick skillet over medium-high heat.
Add the chicken sausage and red onion to the skillet, sautéing for 4-5 minutes until the sausage is browned and the onions are caramelized.
Drizzle the pure maple syrup over the sausage mixture, stirring constantly for 30 seconds to create a sticky glaze.
Add the baby spinach to the pan and toss for 1 minute until just wilted.
Reduce the heat to medium-low and pour in the egg mixture.
Gently scramble the eggs with a silicone spatula, moving them constantly until they are just set and fluffy.
Remove from the heat immediately and serve while hot.
