Place a layer of cooked cabbage leaves over sauce.
Spread half ricotta cheese mixture over cabbage leaves.
Top cheese mixture with half the remaining sauce.
Cover sauce with half the mozzarella cheese.
Top off with additional parmesan cheese if desired.
Bake 350F for about 25 minute
After boiling the cabbage leaves, they should be soft and tender.To speed things up, the cabbage leaves can be steamed in the microwave. Simply place in a microwave-safe bowl along with a couple tablespoons of water and microwave covered on high (100%) for about 6 to 8 minutes. For even cooking, it's best to rearrange the leaves in the middle of the cooking time.
