I had the best pumpkin pie I've ever tasted last fall at the Warrior Run Heritage Festival, and was very surprised when they told me it wasn't pumpkin. I can't even describe how it was better. Just try it if you have the opportunity. Recipes are here or here.
Added bonus: the seeds are about four times bigger than pumpkin seeds and totally yummy. I roasted mine with salt and I can't stop eating them, but that's cool because pumpkin seeds are rich in MUFAS (monounsaturated fatty acids)!
