Grease two 8 x 4 inch pans or 6 mini loaf plans. Preheat oven to 325°F.
In a large bowl, mix together the flour, salt, baking powder, baking soda, nutmeg and cinnamon.
Next, in a separate small bowl, beat the eggs, oil, vanilla extract, and sugars together.
Then, add the wet ingredients to the large bowl of dry ingredients and stir until combined.
After that, grate the zucchini using a box grater. Add to the bread batter, along with the nuts, until well combined. Let batter sit 5-10 minutes.
Proceed to pour the batter into the prepared pans.
Place bread into the oven and bake for 40 to 60 minutes, or until tester inserted in the center comes out clean. My mini-loaf pans take about 35-40 minutes. Large sized loaves take about 55 minutes. (See below for my method on making sure loaves are completely cooked!)
When done cooking, cool in the pan on rack a for 20 minutes. Remove bread from pan, and completely cool. Slice, serve and enjoy!
