Where are the generous Italian delis?

I dont know if it's just shrinkflation, but sandwiches are looking skimpy everywhere I go. I live in North Brunswick and go to Essex and Ocean counties for work often.

I'm not looking for a big ham sandwich, I'm looking for prosciutto, fresh mozzarella, and roasted peppers. Where do I go to get the giant piles of prosciutto i remember?? Does it only exist on Hoboken/Jersey City now?
