My wife can't eat red sauce b/c of reflux so we came up with our own homemade pie which I really like.
We use a very high quality pesto sauce with some extra virgin olive oil.
Then we add fresh tomato slices, mushrooms, spinich, fresh sliced mozzarela and shredded, fresh oregano, basil, tofu, and lucatelli grading cheese.
While I still love a good NY cheese pie, this one is quite excellent and healthy too!
