If you grew up in a normal frum (ashkenazy) home you appreciate a normal shabbos menu: fri nite-gefilte fish with chrain, chicken soup with mandelin, chicken with kugel -shabbos day-gefilte fish again or herring and/or liver, aayer mit zvibbel, p’cha chulent & kugel and maybe some cold cuts.
Sushi & salads for a shabbos seuda is for vegan trendy modern orthodox or baalay t’shuva (still on their way)
