On occasional Thanksgivings-past, we have ended up with the equivalent of 1 whole pie per adult, which was ridiculous and total overkill. I made the Thanksgiving meal and others were in charge of the desserts and we ended up with a ridiculous amount of pie.
A relative will often make pumpkin pie, but their pies are enormous and they don't just make 1, they make 2 pumpkin pies...and there are usually only 2 people at the Thanksgiving dinner table who actually eat pumpkin pie, so I end up throwing most of it out a couple of days later. It's a huge waste.
This year it's different. I grew up in CA on Marie Callendar's pies and I love their dutch apple pie, so I bought one of those. And I got a small 8" pumpkin pie from the grocery store. And vanilla ice cream. That's it.
Sometimes we have a guest with us for Thanksgiving who has celiac disease, so one year I bought a gluten free pie from a local gluten-free bakery. The pie cost me $45! But it tasted really good. Seriously, you couldn't tell it was gluten free. I've attempted to make gluten-free desserts myself, but I always fail miserably.
