Preheat the oven to 350°F. Lightly spray two 8x4-inch loaf pans with nonstick spray.
In a large bowl, combine the sugar, oil, eggs and vanilla. Whisk together well.
In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon and nutmeg. Stir the dry ingredients into the wet mixture; stir just until combined. Gently stir in the pears and the pecans (if using). Divide the batter between the prepared loaf pans.
Bake for 45 to 55 minutes, or until a toothpick inserted into the center of a loaf comes out clean. Allow the loaves to cool in the pans for 10 minutes before removing them to a wire rack to cool completely.
Notes
*To lighten-up this bread a little bit, sub half unsweetened applesauce for half of the oil (½ cup oil and ½ cup applesauce).
Nutritional information does not include the optional pecans.
