Love this. Spanakopita is my favorite food, ever, and I *really* liked the flavor in this. I had to use dried dill, but otherwise made as is. I really liked the flavor the green onion gave this. The only thing I'd do differently next time is not bother with all the layers of phyllo other than a top crust and a bottom crust, because the phyllo kind of "melted" into the filling and couldn't really be tasted anyway.
OMG! This was really, really good. The addition of the mozzarella is brilliant.
