Strawberry Rhubarb Crumble

I had a whole bunch of strawberries that needed to be used, and a bag of rhubarb from my moms garden in the freezer (plus I have a sweet-tooth) so this turned out to be the perfect recipe.

I think there's a typo in the fruit bottom ingredients; it calls for one cup of sugar but doesn't mention it in the preperations, so I just sprinkled the fruit with a bit of sugar, but it doesn't really need it since there's 3/4 cup sugar in the topping.
