Despite being part Irish, my family never really did anything to celebrate St. Patty’s day while growing up. There was no Irish soda bread, no corned beef and cabbage, no colcannon. Since it’s turned into a bit of a foodie holiday, I wanted to make something to celebrate my Irish heritage this year, but there were no family recipes to veganize. I came across an interesting dish in Better Homes and Gardens and it seemed perfect for converting. It’s not really a casserole in the traditional sense, but I wasn’t sure what to call it, and since it’s a casserole dish, I decided to roll with it. If you’re unfamiliar with seitan, it’s a wheat meat that can often be found next to the tofu in the grocery store.
