Okay, so mealtimes in Italy.
Colazione (breakfast): Breakfast is a cup of coffee with milk like a cappuccino. Maybe a croissant or a sandwich (triangular white sandwiches like the triples in Peru). Italians don’t really eat much for breakfast. They consider the milk in the coffee to be the “food.” But, later in the morning, they will have more coffee. Coffee is a small cup of coffee like an espresso. No coffee in Italy is ever the size of American coffees. Italians will have many coffees throughout the day, although milk in coffee is only for breakfast (so before 11 a.m.).
Around 10 or 11 a.m., Italians might have a small snack with their next coffee.
Pranzo (lunch): Lunch is generally eaten from noon to 2 p.m. but on a Sunday, lunch can be later.
Merenda (tea): At around 3 p.m., Italians (and certainly children) will have a snack. One could have a gelato… or some crackers and cheese.
Aperitivo (happy hour): after work, Italians may have a tapas/mezze style spread. Many judge the bar based on the selection of free nibbles. During the current COVID restrictions (restaurants close for in restaurant dining at 6 p.m.), many people are having aperitivo at 3 p.m. Why not?
Cena “che-na” (dinner): Dinner is generally at 8:30 p.m. or later. One had a snack earlier, thankfully.
