Elaine Schmitz, author of Recipes & Recollections of My Greek-American Family, put greetings in her email to me which I asked what they meant. They are below and might be useful if you want to put in a little Italian or Greek into your story’s dialogue.
In Italian:
Buon giorno is Good morning, Buon pomariggio is Good day. Buona notte is Good night.
In Greek:
kalimera is Good morning and kalispera is Good day, kalinikhta is good night.
