I like this recipe:

However, I don't put the filling in the crust used in the recipe. Instead I get a frozen pie crust, defrost it, and then remove it from the tin foil pie dish. Then I put the filling in the foil pie dish, cover it with the pie crust, and bake. When it is completely cool, I wrap tightly with saran wrap and then again with foil and freeze.
I also make veggie burgers and wrap them individually and freeze them too.
