I made this for dinner the other night. Yummy! You can see the pre and post baking pics.
Cut the top off the pumpkin, scrape out the seeds and some of the flesh. Layer thin squares of toast, chopped onion, thinly sliced cheese, salt and pepper in the pumpkin. Replace the top and bake in a slow oven 2-3 hours. Remove top, stir contents, add hot milk and serve with extra milk for bowls, to make a soup consistency. And enjoy.
