Cabbage and Potato Gratin with Sage

I found this recipe on Deborah Madison's blog. Deborah just happens to be one of my favorite vegetarian cooking authors. I own two of her cookbooks - Vegetarian Cooking for Everyone (my very first vegetarian cookbook) and The Greens Cookbook. I confess that I study her cooking methods religiously and heavily rely on her recipes for my weekly meal plans. Thanks Mike for the best Valentine's gift ever!
