I think pumpkin might be another word for the winter squashes and gourds, at least, I've heard it referred to that way in parts of central and eastern europe.
I purchased honeynut squash the other day at the store. Wow, delicious!
Earlier this year I discovered a recipe on BA that was an egg and dairy free "carbonara". I tried this for fun, and even made it accidentally vegan by rehydrating dried shiitake mushrooms then frying them until crispy since I didn't have any bacon. While delicious, it was no carbonara, and if I were to make it again, use a different squash since butternut and kabocha are a bit too sweet.. maybe acorn or spaghetti squash would be better. Appears to be similar to the risotto posted earlier in this thread.
