Pumpkin Apple Muffins

1 cup all-purpose flour
2/3 cup whole wheat flour
1 cup sugar
2 tsp pumpkin pie spice (or 1 tsp cinnamon, 1 tsp pumpkin pie spice)
3/4 baking soda
1/4 tsp salt
1 egg, lightly beaten
2/3 cup pumpkin puree
1/3 cup vegetable oil
1 1/3 cup peeled and chopped apple

1. Preheat oven to 350.  Lightly grease 12 muffin cups or use paper liners.
2. In a large bowl, sift together flour, sugar, pumpkin pie spice, baking soda, and salt.  In a separate bowl, mix together eggs, pumpkin, and oil.  Add pumpkin mixture to flour mixture; stirring just to moisten.  Fold in apples.  Spoon batter into prepared cups.
3. Bake in preheated oven for 25 to 30 minutes, or until a toothpick inserted into a muffin comes out clean.

I halved the amount of sugar (to 1/2 cup), and used some brown sugar because I had run out of white sugar.
