Yes, that time of year is coming up fast! Time to come up with some new Passover recipes for vegetarians. I have one today, and I think there will be one or two more this week or next.
This recipe is based on one from The Healthy Jewish Cookbook, which my mother gave me last year. It's a very simple recipe, well-suited for making after a long day at work: sliced zucchini and tomato over a layer of shredded mozzerella on a bed of sauteed onion and garlic. The original recipe uses fresh mozzerella, but I've never seen fresh mozzerella certified kosher for Passover, so I made some changes to make it work with shredded mozzerella.
This recipe is not vegan (contains cheese), but it is gluten-free and non-gebrochts (contains no matzah). I suppose you could make it vegan by substituting some chopped or ground nuts for the cheeses, but I haven't tried that, so I don't know hwo well it would work.
