In a large bowl, combine flour, baking soda, cinnamon, nutmeg, cloves, salt and nuts.
Open eggs, one at at time into a ramekin to check. This makes it easier to remove bits of shell, if needed. After each egg, pour into a mixing bowl.
Add oil, sugars, yogurt, vanilla, apples and zucchini.
Preheat oven to 350
Pour liquid ingredients over dry ingredients; mix well.
Spoon into 3 greased 8x4-in. loaf pans or 8 small loaf pans.
Bake at 350° until a toothpick inserted in center comes out clean, 50-55 minutes for large loaf pans, 40 - 45 minutes for small loaf pans.
Cool in pans for 10 minutes before removing to a wire rack to cool completely. Be sure they are completely cool before wrapping.
