Start by breaking up the sausage in a pan with a drizzle of oil. Add the leek and a splash of water and let it simmer.
Now add the Gorgonzola Dolce Igor until it melts.
Meanwhile, we cook our snails in water for 7 minutes and then let them cool.
We take the mixture we made earlier and fill our lumaconi. We spread the remaining mixture on top.
Cover with a layer of grated Parmesan cheese.
Finally, we cook everything in the oven until gratinated.
