Preheat your oven to 400°F and lightly grease a small oven-safe baking dish.
Peel the sweet potato and dice it into small half-inch cubes for even cooking.
Toss the sweet potato cubes with olive oil, sea salt, black pepper, and garlic powder on a parchment-lined baking sheet.
Roast the sweet potatoes for 15 minutes until they are tender and slightly browned.
While the potatoes roast, brown the ground turkey in a skillet over medium heat until fully cooked through.
Steam the broccoli florets until bright green and tender-crisp, then finely chop the red bell pepper.
In a medium bowl, whisk together the large eggs, egg whites, and dried oregano until well combined.
Layer the roasted sweet potatoes, browned turkey, steamed broccoli, and chopped peppers into the prepared baking dish.
Pour the egg mixture over the top, gently shaking the dish to ensure the liquid reaches the bottom.
Reduce oven temperature to 375°F and bake for 20 to 25 minutes until the eggs are set and the top is golden.
Allow the bake to rest for 5 minutes before topping with fresh avocado slices and serving.
