Grease and flour a standard 8x5" loaf pan. You can also coat it with my handy baking spray replacement. (See the link in the blog post) Set it aside for now.
Combine the flour, salt, baking soda, and baking powder in a small bowl. Give those a stir and set it aside.
Put the sugar in a mixing bowl.
Using your microplaner or other utensil, zest the lemon into the mixing bowl. You'll zest the whole lemon.
Juice your lemon and add 2 teaspoons of the juice to the mixing bowl. Reserve the remaining juice for later.
Add the apple sauce, extra virgin olive oil, vanilla extract, and eggs to the mixing bowl. Whisk until smooth.
Add in your dry ingredients and whisk smooth.
Stir in the shredded zucchini.
Spread the batter into your loaf pan.
Bake for 1 hour, or until the loaf tests done when tested with a wooden pick.
Place the pan on a cooling rack and let the loaf cool for 5 minutes in the pan.
Remove the loaf to the cooling rack and cool completely.
For the Glaze
Combine the powdered sugar, lemon juice, vanilla extract, and milk. Whisk smooth.
Drizzle over the lemon zucchini bread.
Enjoy!

Notes
This lemon zucchini bread freezes well. Try doubling the recipe, and freeze one for later. If you freeze it, do not add the glaze at this time. Wait until you thaw it out to make the glaze, and add it then.
