Commercial or home use? I am guessing commercial due to you mentioning Sysco.
Different regions for Sysco carry different products, Their Sysco branded products are iffy at best, and then the use brand names like "Arrezzio" and other Italian sounding names for some of the Sysco products to mislead you.
Everything I could ever want in Italian branded products is carried by a company named Greco & Sons distributing located in northern IL, and Southern WI, but they do not deliver up where I am at, So I am trying work out a deal with a distributor that does come up here to bring products handled by Greco with them and to not see a huge increase in cost. Anything to not need to do the drive myself to get product.
I would suggest going to an Italian Deli looking around and writing down brand names such as "Volpi" and the other classic makers of cured meat products.
Hormel has actually came a long way in the last 10-15 years with their Italian style products, Check into their stuff too, You may be surprised.
Even a local specialty store may help you get brand names, then you can contact the manufacturer of those brands to find distributors in your area.
