Also the word lasagne (which people here pronounce lasagna) is plural.
Lasagne is the plural plural of lasagna.
Spaghetti is the plural of spaghetto.

Oh, nearly forgot, scampi really is the plural of scampo. But when you ask for scampi you want more than one. If you ask for a panini (more than one), it's really a panino (only one) that you want.
