I love these
Pumpkin Carob Chip Muffins, though I usually use raisins instead of carob chips.
I've got a delicious recipe that I adapted from the book Passionate Vegetarian, for Sweet Baked Pumpkin. Cut pumpkin into large pieces. Toss with melted vegan margarine, soy sauce, sweetener of choice (I like maple syrup), salt, pepper and paprika. You can add some orange juice too. Bake in a 200C/400F oven until tender.
The original recipe has you cut the pumpkin so you have curved/hollow pieces. You add all the toppings to the curve/hollow and bake it, then mash the toppings in at the end once they're baked. Both ways are super, super tasty. I usually like to just toss it all together though, it's a little bit less fiddly.
