1. In a bowl, mix flour, sugar, baking powder, salt, and nutmeg.
2. In another bowl, mix eggs, milk, applesauce, and oil; add to dry ingredients and stir just until batter is evenly moistened.
3. Turn a waffle iron to high heat and spray both sides with cooking oil spray. When it's hot, add about 1 1/4 cups batter; close iron and cook until waffle is well browned, about 9 minutes. Remove waffle and serve, or keep warm in a single layer on a baking sheet in a 200° oven up to 15 minutes. Repeat to cook remaining waffles. Serve with maple syrup.
