This is legit, just like how it's served in Italy. You can add a dash of panko (breadcrumbs) at the end if you want. My grandmother (italian living in italy) did not make it with lemon, so I omit that. Using red chili flakes instead of fresh chili pepper is perfectly acceptable as well. You do not add cheese to this recipe!! I mean you can... but that's not the traditional way of serving this dish.
