Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Place the diced red bell pepper, small broccoli florets, and red onion on the baking sheet and toss with avocado oil, sea salt, and black pepper.
Spread the vegetables in a single layer and roast for 15 to 18 minutes until they are tender and slightly charred.
In a medium mixing bowl, whisk together the large eggs, liquid egg whites, and garlic powder until the mixture is well combined and frothy.
Heat the ghee in a large non-stick skillet over medium-low heat until melted and coating the bottom of the pan.
Pour the egg mixture into the skillet and cook slowly, using a silicone spatula to gently push the curds from the edges toward the center.
Once the eggs are soft and just set, remove the roasted vegetables from the oven and fold them gently into the scramble.
Transfer the hearty scramble to a plate and enjoy immediately while warm.
