Two I used for the first time this year:
Over apple cider: "Yehi ratzon ... sheta'azreinu leSADER et chayyeinu." - "May it be the Will of God ... that You help us order our lives."
Over papaya: "Yehi ratzo ... sheteracheim 'aleinu keracheim AV 'al banim." - "May it be the Will of God ... that You have mercy on us as a FATHER has mercy on his children."
