Preheat oven to 350℉. Gather you ingredients so that you have everything close at hand on the counter or table. Spray two 9-inch loaf pans with baking spray.
Prepare the Zucchini
Using a box grater, shred peeled zucchini into a bowl. Do not squeeze dry. Set aside.
Make the Batter
In a large mixing bowl, combine granulated sugar, large eggs, vegetable oil, and vanilla extract. Beat well.
In small bowl mix together the all-purpose flour, salt, baking powder, baking soda, ground cinnamon, and nutmeg.
Stir the flour into the egg mixture until moistened. Fold in shredded zucchini and crushed pineapple until incorporated.
Pour batter into prepared loaf pans. Bake in preheated oven for 60-65 minutes or until a toothpick inserted into the center of loaves comes out clean. Cool for 10 minutes. Then remove from pans and cool on a wire rack. Makes 2 loaves.
