Yum! A few subs based on what I had on hand... fresh basil instead of parsley, fresh grated parmasean instead of Romano, and panko breadcrumbs. Doubled the red pepper flakes because we like spicy. Added 1 tbsp corn starch to broth before adding to thicken up sauce. Did half again as much for the sauce. Squeeze half a lemon instead of slices. Put spaghetti in the pan and happened to pop back in the oven to stay warm until everyone was ready to eat and the noodles soaked up all the sauce perfectly!
