Apple Crisp

4 cups sliced, peeled (or not) apples (approx. 4 apples)
1 cup brown sugar
3/4 cups flour
3/4 cups oatmeal
1 tsp cinnamon
1 tsp nutmeg
1 stick butter

Preheat oven to 375 degrees. Grease (or don't) a 9x9 pan. Place sliced apples on bottom of pan. Mix dry ingredients (I do it in a ziplock bag), then add butter. Mix well. Sprinkle mixture over apples. Bake for 30 minutes. Remove from oven. Serve warm with or without vanilla ice cream.
