I mean...no....quiche is a custard base with cheese and no top crust. A chicken pot pie uses a roux with no cheese and a top crust.

The top crust is not really that big a deal, but custard vs roux is significant. Also, cheese.

The veggie mixture tends to be very different too, but that is pretty flexible for quiche and I'm sure a quiche with similar veggies to a pot pie would be good, but I don't think it would be a traditional flavor profile.

I’d say it was worth three shots 😉

I mean, if these are caused by sinkholes, then that should have been addressed during construction. Roads can be very thick and are made of lots of different layers, each of which should be compacted very regularly and thoroughly during construction. If sink holes are common in the area, then they should have designed countermeasures to minimize their impact. My understanding of sinkholes, is that they typically form due to water phase erosion, which again, should have been known and at least partially accounted for. But, hey, I’m not a civil engineer, so I could wrong, but those definitely seem more likely to be potholes as opposed to sinkholes.
