If you catch her, she has to grant you three wishes. Good luck catching her though.
In previous years, I've made a seitan or soy curl mixture that I "corned" with typical corned beef flavor. This year, I'm going to have to find a gluten-free delight. It's really about the carrots, potatoes, and cabbage anyway. I've been cruising lentil loaf on Pinterest, and I think that's going to be the perfect vehicle for my "corned" spices.
I found some sorghum beer, since I've read that gluten stays in your system for a long time and I'm still nursing, so green beer can still be on the menu. I don't think any Guiness is vegan, and I know it's not gluten-free... so that's out of the question.
What else? What are your St. Patty's traditions?
