1Preheat the oven to 375 degrees F. Coat 2 (4 1/2 by 8 1/2-inch) loaf pans with nonstick spray. Line the pans with parchment paper and spray the paper.
2Combine the zucchini, apple, brown sugar, oil, eggs and vanilla extract in a large bowl and stir to combine.
3In another bowl combine 3 cups flour, salt, baking powder, baking soda, cinnamon and nutmeg to the bowl and mix well.
4In a small bowl toss the nuts with the remaining 1/2 teaspoon flour to coat and prevent them from sinking. Gently stir in the nuts. *I only added about 1/2 cup of nuts. I used pecans but you can use any nut you like and add as much as you like.*
5Divide the batter between the 2 loaf pans. Bake until a toothpick or skewer inserted in the middle of each loaf comes out clean, 45 minutes to 1 hour. Remove the bread from the pans and cool on a wire rack.
