Besides wearing clean nicer weekday clothes (not bigdei shabbos), wife prepares a special, delicious meal for supper (not necessarily a fruit themed menu), and for dessert we have nice delicious fruits, including fruits from the 7 minim. We used to include lots of nuts, but one child is allergic, so we substitute other yummies like fruit candy, and nosh.
We try to make it somewhat of a special night, teaching the kids what it’s all about, and the ‘miracle’ of fruits. We can teach the meaning of a brocho, and the delight Hashem has from each bracha, we tell how Tatty davens for a nice esrog, and describe the 7 minim, etc.
