Citterio brand cold cuts are part of an old and glorious Italian house established in the 19th century. For about a generation, they have been producing their meats in the United States, upholding the quality standards of the old country. I have personally tried their prosciutto and their bresaola, both of which were very good (but not cheap). This is an excellent alternative when you don't have the time or the access to a deli with real Italian products that are cut to order. I have found this brand at Trader Joe's and Shaw's in the Boston area.
The appropriate words for cold cuts in Italian are salumi (not to be confused with salami, which is just one type of salumi). In Italy they are also called affettati (from affettare, to slice)- although in theory this could also include other sliced-to-order stuff, such as cheese.
