Preheat your oven to 400°F.
In a bowl, combine the lean ground beef with the egg white, salt, and pepper. Form the mixture into small meatballs, about 1 to 1.5 inches in diameter.
Place the meatballs on a baking sheet lined with parchment paper and bake for 15-18 minutes until they are cooked through and lightly browned.
While the meatballs are baking, prepare the tomato sauce. Finely chop the fresh tomatoes, garlic, basil, and oregano.
Heat the olive oil in a small saucepan over medium heat. Sauté the garlic for about 1 minute until fragrant, then add the chopped tomatoes and herbs. Simmer for 5-7 minutes, stirring occasionally, until the sauce thickens slightly. Season with salt and pepper to taste.
Spiralize the zucchini into noodles or use a vegetable peeler to create thin strips.
To serve, plate the zucchini noodles and top with the baked meatballs. Spoon the warm herb tomato sauce over the meatballs and noodles.
Enjoy this light, nutritious dish as a satisfying meal any time of the day.
