Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the red potatoes into small cubes and toss them with half the avocado oil, sea salt, and black pepper.
Spread the potatoes on the baking sheet and roast for 20 to 25 minutes until they are tender and golden brown.
While the potatoes roast, slice the chicken sausage into rounds and finely dice the onion and garlic.
Heat the remaining avocado oil in a non-stick skillet over medium heat and sauté the sausage, onion, and garlic until the onion is translucent.
Whisk the whole egg and egg whites together in a small bowl until well combined.
Add the cherry tomatoes to the skillet and cook for 2 minutes until they begin to soften.
Pour the egg mixture into the skillet and cook, stirring gently, until the eggs are just set and fluffy.
Serve the scramble alongside the roasted potatoes and garnish with fresh herbs if desired.
