Preheat oven to 350°F and grease a 9x5-inch loaf pan.
In a medium bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg.
In a large bowl, beat together oil and sugar until well combined, then add eggs one at a time, mixing well after each addition.
Stir in pear sauce and vanilla extract until smooth.
Gradually fold the dry ingredients into the wet ingredients until just combined, being careful not to overmix.
Pour batter into prepared loaf pan and bake for 55-60 minutes, or until a toothpick inserted in the center comes out clean.
Allow bread to cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely before slicing.
