Preheat your oven to 400°F (200°C).
On a large baking sheet, toss the chopped bell pepper, diced zucchini, and sliced red onion with 1 teaspoon of olive oil, garlic powder, and half of the sea salt and black pepper.
Spread the vegetables in a single layer and roast for 15-20 minutes until they are tender and slightly charred.
While the vegetables roast, whisk together the whole eggs and liquid egg whites in a medium bowl until well combined and frothy.
Heat the remaining 1 teaspoon of olive oil in a non-stick skillet over medium-low heat.
Pour the egg mixture into the skillet and cook, stirring gently with a silicone spatula, until the eggs are just set and fluffy.
Season the scrambled eggs with the remaining sea salt and black pepper.
Plate the eggs alongside the roasted vegetables and serve immediately while hot.
