Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Toss the diced bell pepper, zucchini, and red onion with olive oil, sea salt, black pepper, and garlic powder.
Spread the vegetables in a single layer and roast for 15 minutes until they are tender and slightly charred.
While the vegetables roast, heat a non-stick skillet over medium heat and cook the ground turkey until browned and crumbly.
In a medium bowl, whisk together the whole eggs and liquid egg whites until well combined and frothy.
Stir the roasted vegetables and fresh baby spinach into the skillet with the turkey, cooking for 1 minute until the spinach wilts.
Reduce the heat to medium-low and pour in the egg mixture, stirring slowly with a spatula to create soft, creamy curds.
Once the eggs are just set, remove from heat and fold in the crumbled feta cheese before serving immediately.
