Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Place the diced red bell pepper, red onion, and small broccoli florets onto the baking sheet and drizzle with olive oil.
Sprinkle the vegetables with the garlic powder, half of the sea salt, and half of the black pepper, then toss to coat evenly.
Roast the vegetables in the oven for 15 to 20 minutes until they are tender and show golden-brown caramelized edges.
While the vegetables roast, whisk the large eggs, liquid egg whites, and cottage cheese in a bowl with the remaining salt and pepper until well combined.
Heat a large non-stick skillet over medium-low heat and pour in the egg mixture, letting it sit for 30 seconds before gently stirring.
Continue to cook the eggs, stirring occasionally to create large, soft curds, until they are just set and still look slightly moist.
Gently fold the roasted vegetables into the scrambled eggs and serve immediately while warm.
