Yes, of course you can. I do want to say the this dish is flavorful all on it's own though. You can add Parmesan, Asiago or Romano cheese. These are hard cheeses that pack a powerful, flavorful punch. I also added Feta cheese once (because I love Feta and want to put it on everything!) but I think I liked it better with the harder cheese. But that's just a personal preference.
