I am going to use a 1/2 bag frozen mixed veggies, 1 can of cream of mushroom soup with 1/2 can milk, 2 cups of chicken and pour a biscuit mix on the top for the crust. Of course I will bake it according to box directions. Do you think this will work ok? I dont want to buy a $4 box of baking mix at the store since I rarely use it. Any suggestions?

Do you have any all purpose flour? You can make a crust with APC, an egg and some water... mix it into a ball and refrigerater for 30 mintues then roll it out into a crust. If you want a flaky crust, use some butter or shortning to make it with.

I know it will work well!! this is basically what I have been doing for years to make potpie casseroles!!
