Step by step

Add a layer of lasagna and then one of pumpkin sauce

Tips
Avoid recipes that suggest a combination of pumpkin and gorgonzola cheese: the strong flavour of the gorgonzola would dominate the delicate taste of the pumpkin.
Trivia
Did you know that there are at least twenty varieties of edible pumpkin? The best-known is perhaps that from the province of Mantua. There are also many non-edible pumpkins, usually used for ornamental purposes.
