Thank you very much for creating and sharing this lovely puzzle. I gave 3* as I haven’t any experience with this combination of constraints.

Absolutely brilliant, I loved every minute, even the Sudoku at the end didn't spoilt the experience. Probably more veering two star difficulty though (or I might just have too much experience with regular sandwiches to find it easier).
Thank you!
