Another puzzle from Jess! (More Jess puzzles are here.) Very apt theme on this one, chag sameach y'all!!

Jess says: "I love having a theme for these mini puzzles so I'm not just staring at blank squares. When I realized passover was approaching and the March 27th / 14th of Nissan / night before passover puzzle wasn't taken, I knew I had to write one. I recommend starting with the downs (or doing a downs-only solve (?!)) to get to the theme words."
