Preheat the oven to 350 degrees.
Liberally grease a standard loaf pan. Set aside.
In a large bowl, whisk together the eggs, sugar, and oil until well blended.
Add the flour, baking powder, baking soda, salt, nutmeg, and shredded zucchini and stir well until completely incorporated.
Fold in nuts if desired.
Transfer the batter to the prepared loaf pan.
Bake 50-55 minutes or until a toothpick test comes out mostly clean, with just a few crumbles.
