Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the diced red bell pepper, zucchini, and red onion on the baking sheet with 1 teaspoon of olive oil, sea salt, and black pepper.
Roast the vegetables for 15 to 20 minutes until they are tender and slightly caramelized around the edges.
In a medium bowl, whisk together the eggs, egg whites, and garlic powder until the mixture is well combined and slightly frothy.
Heat the remaining 1 teaspoon of olive oil in a large non-stick skillet over medium heat.
Add the roasted vegetables and the rinsed black beans to the skillet, stirring for 1 minute to warm them through.
Pour the egg mixture over the vegetables and beans, then cook while stirring gently until the eggs are just set and fluffy.
