This is one of those super simple dinners that started out as a vague idea and ended up as a complete masterpiece. I went to the store knowing only that I wanted to make something with pasta and canned pumpkin. I picked up a few basic ingredients like broth and arugula and a few new-to-me items like grana padano, a hard, nutty cheese that's a little milder than parmisiano reggiano, and perciatelli, a delightfully squishy pasta that's like bucatini's thinner cousin, and started playing. The result was a quick (20 minutes, most of which is spent waiting for water to boil) dinner that's perfect as a satisfying dinner for one, a romantic dinner for two, or a crowd pleaser for an impromptu dinner party.
