I usually use blueberries for this, but any kind of berry will do.
I take a pyrex baking dish and slice a lot of peaches up in it. I add lots of berries to them and mix them up. (Use lots of fruit) Then I take 1/2 cup of brown sugar, 1/2 cup of flour, 1/2 cup of oatmeal, some cinnamon, mace, nutmeg and 1 stick of cold butter. I mix the dry ingredients and cut in the butter till I get a crumbly mixture. Then I sprinkle the crumbs all over the top of the fruit. Bake for 30 min at about 350 degrees F. or till brown around the edges. Serve warm with ice cream.
YUMMY
