Preheat oven to 400 degrees F.
Mix the ingredients for the fruit mixture together in a large bowl. **Never used alternative sweeteners, you may have to experiment with amounts if you do. Spread evenly into a 2-quart casserole dish. Set aside.
Mix the dry ingredients for the topping together in a medium bowl. Cut in the margarine until the mixture resembles small peas. Spread the topping evenly over the fruit mixture.
Bake for 35-45 minutes, until bubbly.
Serve warm with your favorite vegan "ice cream"
Note: I have changed the fruit in this many times. This is the original recipe, but I have made it with fresh peaches and blueberries and it was quite good. Go wild, let your imagination take over and reward your taste buds.
