How come Chandler suddenly mentioned about "Italy"?

Chandler is making a joke here. Joey's kitchen is filled with all types of tomato and tomato sauces, so Chandler jokes that "Italy called and said it was hungry." Italy is famous for pasta and tomatoes, so he is implying here that either Joey used up so many tomatoes that there are none left in Italy, or he has made so many tomato sauces that Italians will be hungry to have a taste.
