If we're talking fruit pies I'd probably be very generic and say a nice apple pie would be my favorite go-to.
Of course for regional pies, the most common pie I see around the state the most is a vegetable pie known as rhubarb. A nice rhubarb and wild berry pie can be enjoyably tart and sour with that delectable hint of sweetness that rounds out the sharpness of the ingredients.
Dumping mashed potatoes on a can of beans and browning the top with a blowtorch like it's a flan: "Behold, a pie!"

still better than what passes for an apple pie in this godforsaken country
