Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Dice the red bell pepper, zucchini, and chicken sausage into uniform bite-sized pieces.
Toss the diced vegetables and sausage on the baking sheet with avocado oil, sea salt, and black pepper.
Roast for 12 to 15 minutes until the vegetables are tender and the sausage is slightly browned and caramelized.
While the vegetables roast, whisk together the whole eggs, liquid egg whites, and nutritional yeast in a medium bowl until well combined.
Heat a non-stick skillet over medium-low heat and add the roasted vegetable and sausage mixture along with the baby spinach.
Once the spinach has slightly wilted, pour the egg mixture into the skillet.
Gently stir the eggs with a silicone spatula, moving them constantly until they are just set and have a velvety texture.
