Preheat your oven to 400°F.
In a bowl, combine the lean ground turkey with the egg white, one minced garlic clove, dried oregano, and a pinch of salt and pepper. Mix gently until just combined.
Form the mixture into small meatballs, about 1 to 1.5 inches in diameter, and place them on a baking tray lined with parchment paper.
Bake the meatballs in the oven for 15-18 minutes, or until they are fully cooked and lightly browned.
While the meatballs bake, spiralize the zucchini to create spaghetti. Set aside.
In a medium saucepan, heat the olive oil over medium heat. Sauté the remaining minced garlic for about 30 seconds until fragrant.
Add the tomato sauce to the saucepan and let it simmer for 5 minutes. Season with salt and pepper to taste.
Lightly toss the zucchini spaghetti in the sauce, allowing it to warm just slightly while remaining crisp.
Plate the zucchini spaghetti, top with the baked turkey meatballs, and finish with a drizzle of tomato sauce over the top.
Serve immediately, enjoying a balanced dish that's low in calories yet high in protein.
