Preheat your oven to 400°F (200°C).
Toss the cubed sweet potatoes with 1 tablespoon of avocado oil and a pinch of sea salt, then spread them on a parchment-lined baking sheet.
Roast the sweet potatoes for 25-30 minutes or until they are tender and caramelized on the edges.
While the potatoes roast, heat the remaining avocado oil in a non-stick skillet over medium heat.
Add the turkey sausage to the skillet, breaking it apart with a spatula, and cook until browned and crispy.
Lower the heat slightly and add the fresh spinach to the skillet, sautéing until just wilted.
Pour the egg whites into the skillet with the sausage and spinach, stirring gently until the whites are fully set and fluffy.
Plate the roasted sweet potatoes and top them with the turkey sausage and egg white scramble.
Garnish with the fresh avocado slices and serve immediately.
