OK, finally got around to making this again.
I pulled a recipe from Taste of Home as a guide to ingredients, but not quantities. I played around with those as I felt necessary.
I also parboiled the cabbage for about 2 minutes to make sure that it would properly cook in the casserole.
Finally, I used a combination of Colby & Monterrey Jack cheese instead of Mozzarella. Turned out VERY VERY good, but the spice balances are a bit off. I'll need to mess with them some.
