In a bowl, combine the ricotta, provolone, parmesan and italian seasoning. Mix until combined. Place a tablespoon or so on each slice of zucchini and carefully roll each up, placing it in the baking dish. If your zucchini breaks – no big deal! It will still come out great. Repeat with the remaining zucchini and ricotta. I like to put 9 to 12 pieces in this dish, based on the size of the zucchini. If you want to make a 9×13 dish, I would double (at least!) the ricotta mixture.
