Pre heat the oven's broiler with rack set about 8-inches from heat element.
Place pan over high heat and lower to medium-low as soon as you hear the oil sizzle. Let leftover pasta pizza continue to cook for about 2-minutes. Sprinkle mozzarella and parmesan over top and immediately transfer pan ( pan is hot, careful) in to the oven. Continue to cook until cheese melts ( Keep a very close eye, since it will go from melted to burned in a few seconds ).
Transfer pan on to a wire rack and sprinkle chopped fresh basil on top. After about 3-5 minutes, loosen the edges with a rubber spatula and gently transfer pizza onto a cutting board and cut into slices.
