Place the oven rack in the middle position and preheat the oven to 350℉. Spray two 8x4 inch loaf pans with nonstick spray.
In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, allspice and salt.
In a large bowl, whisk together the eggs, applesauce, oil, sugars, and vanilla. Stir in the zucchini and pineapple. Then stir in the dry ingredients, a little at a time, just until the batter is moistened and incorporated. Don't over-mix.
Divide the batter between the two prepared loaf pans. Bake 50 to 60 minutes, or until the edges pull away slightly from the sides of the pan and a toothpick inserted in the center comes out clean. Let the bread cool in the pans for at least 20 minutes before removing them to a wire rack to cool completely. This bread will keep well at room temperature for up to three days.
