Slice 4 zucchini lengthwise, not too thinly.(Mine were about 8 in. long and about 2 in in diameter).
Spray a square baking pan and put in one layer of zucchini. Spoon over about 2 tbsps heavy whipping cream and top with shredded romano and parmesan cheese, repeat layers, like lasagna. Finish off with cheese and cream. Bake at 425 until golden brown and slightly crusty on top. This is awesomely delicious!
