Preheat the oven to 375°.
Make the filling by combining all the filling ingredients EXCEPT for the prosecco (or sparkling wine) together in a large bowl. Toss together with a large spatula until the tapioca starch is dissolved and the sugar and honey are well blended. Add the prosecco and stir gently.
Lightly spray a 3 quart (9 x 13 x 2-inch) pan with cooking oil. Pour filling into the pan. Place pan on a rimmed baking sheet for overflow.
Bake in oven for 20 minutes.
You can substitute an equal amount of champagne or other sparkling wine for the prosecco.
