For a Blueberry Crisp just substitute one quart of blueberries for the apples. You might want to forget about the cheddar cheese with the blueberries.
Easy Old Fashion Apple Crisp
3 or 4 tart cooking apples
Arrange apples, pared, cored, and thinly sliced in a well-buttered shallow baking dish. Melt the butter and stir in the sugar, oatmeal, flour, and cinnamon until well mixed. Sprinkle over the apples. Bake in a 350 degrees oven for 45 minutes or until crust is golden brown and the apples are soft. Serve the crisp warm with whipped cream, vanilla ice cream or my personal favorite, thinly sliced cheddar cheese.
