Preheat oven to 350 F. Grease a 9- x 5- x 3-inch loaf pan or large muffin tins. In a medium bowl, whisk together flour, salt, cinnamon, and nutmeg until combined. Set aside.
In a large bowl, beat eggs, sugars, vegetable oil, sour cream, and vanilla. Stir in banana. Using a wooden spoon, stir in flour mixture, mixing only until combined. (Small lumps will bake out.) Fold in zucchini and pecans.
Pour into prepared loaf pan or muffin tins. Bake about 45 minutes to 1 hour for the loaf and about 25 to 30 minutes for the muffins, until center tests done with a toothpick. Let rest in pan for 5 minutes, then turn onto a rack to cool. Best served warm or at room temperature. Yield: 1 loaf or 12 muffins
