    The evening will feature engaging conversations, performances, and, of course, a wide array of delicious dishes! We’re excited to see the recipes you’ll bring and to celebrate the richness of our diverse cultures and heritages together. We will share an RSVP and potluck sign-up in the coming weeks!
