I like a spiced pumpkin risotto. I take a basic butternut squash risotto recipe substitute pumpkin and add ginger. I bake my pumpkin in 1 inch cubes with rosemary, cardamom, salt and pepper. If I am just cooking for my wife and I as opposed to cooking with my kids in mind, I add chiles to the risotto, it cuts some of the sweet out of the pumpkin.

edit: You could leave the cardamom out, I just really like the flavor so it is more of a personal choice.
