There are so many lovely things to eat while in Italy, you don’t want to miss a meal! The main meals in Italian are:
Breakfast: La colazione
Lunch: Il pranzo
Dinner: La cena
If you are hungry outside of these times and fancy a snack, you could use the following words:
uno spuntino / uno snack (both mean snack)
una merenda (often used for afternoon snack or tea)
stuzzichino (also means canapé)
Buon appetito!
