Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with avocado oil and a pinch of sea salt, then spread them in a single layer on the baking sheet.
Roast the sweet potatoes for 20-25 minutes, flipping halfway through, until they are tender and golden brown.
In a small bowl, whisk together the three whole eggs and the egg white until the mixture is uniform and slightly frothy.
Heat a non-stick skillet over medium heat and add the ghee, swirling to coat the pan.
Add the fresh spinach to the skillet and sauté for 1-2 minutes until just wilted, then remove the spinach from the pan and set aside.
Reduce the heat to medium-low and pour the egg mixture into the same skillet.
Cook the eggs by stirring gently with a spatula until they form soft, fluffy curds.
Serve the warm scrambled eggs alongside the roasted sweet potatoes and sautéed spinach.
