Preheat your oven to 400°F (200°C).
In a bowl, combine the ground turkey, egg white, dried oregano, dried basil, garlic powder, salt, and pepper. Mix until evenly incorporated.
Form the turkey mixture into small meatballs, approximately the size of a golf ball.
Chop the zucchini, red bell pepper, and red onion into bite-sized pieces.
In a separate bowl, toss the chopped vegetables with olive oil, a pinch of salt, and pepper.
Arrange the turkey meatballs on a baking sheet lined with parchment paper and spread the vegetables around them in a single layer.
Roast in the preheated oven for 20-25 minutes, or until the meatballs are fully cooked (internal temperature of 165°F) and the vegetables are tender and slightly caramelized.
Serve warm and enjoy your balanced, protein-rich meal.
