Whoa, now this piqued my interest. I may try my hand at this in the very near future. May try replacing the biscuits with some cornbread or polenta though, not really feeling the biscuits.
Replace it with crunched up Corn Chips...
Cornbread, without a doubt.
I think the only way to have it look like a real pot pie would be to make a drier, higher fat, cornbread batter more akin to a pie crust than cornbread. Look up cornbread crust or cornmeal crust. Will have pretty much the same flavor, but, not the texture.
I love pot pie. This recipe kinda got lost in the shuffle. I'll have to make this, sometime soon.Really like Chicken Pot Pie!
