Heat the avocado oil in a large non-stick skillet over medium heat.
Add the diced sweet potatoes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and golden brown.
Stir in the sliced chicken sausage, diced onions, and red bell peppers, sautéing for another 5 minutes until the sausage is browned and vegetables are soft.
In a small bowl, whisk together the whole eggs, liquid egg whites, sea salt, black pepper, and garlic powder.
Lower the heat to medium-low and add the baby spinach to the skillet, stirring until the leaves are just wilted.
Pour the egg mixture over the sausage and vegetables, scrambling gently with a spatula until the eggs are fully set and fluffy.
Remove from heat, garnish with fresh chopped chives, and serve warm.
