Strawberry Rhubarb Crumble Pie

I have been craving a rhubarb pie since March, and I finally took the time to make one yesterday.  Surprisingly, there was not a lot of rhubarb to be found at our grocery store...are we already past rhubarb season by mid-April?  Maybe everyone else, like me, had the urge to make some tangy dessert with rhubarb.  Well, in the end, I'm just glad I was able to grab some, mix it up with some strawberries, sugar, the juice of a 1/2 and the zest of a full lemon, some tapioca pearls, and a crumble topping to come up with what you see below.  Happy Spring!
