Grape leaves are nice, Assorted Grilled vegetables, Perhaps some Kibbe, Cigars, or Lachmagin if you are serving fleishig (meat).
A jello* mold with fruit or just a simple Fruit Platter is nice. Also a Crudite' platter with a dip.
Top it all off with some Yerushalmi Kugel , or an overnight Potato Kugel always goes over big. Good Luck!
* “Jello” is used in the generic sense, and not the brand name. For example, Lieber’s, Gefen, Kojel, Mishpacha make a kosher jello.
