I added prosciutto! And the arugula just kind of wilts at the end hahaha

I do love prosciutto. Though I sort of think of it as a meat-based "herb" rather than meat itself, unless I'm really gorging on it. More there to accent flavor than really provide a decent chunk of protein.
I suspect serving cacio e pepe alongside something like chicken saltimbocca would scratch my meat itch though.
