The problem with those super sized subs is that, invariably, they are made on this huge soft crappy excuse for a roll. There is so much bread on this thing that the sandwich fillings are completely overwhelmed. All you taste is bread, bread and bread.
Recently, I hosted some folks at my house and opted for three regular long loaves of italian bread from The Riviera on Harlem near Belmont.
The result was enough sandwich to feed an army, quality meats, cheeses and bread. It tasted like a sandwich rather than a big loaf of store bought bread. The cost was even a bit less than those six foot monstrosities.
I had six feet of sub (in three pieces) for under $75. One Will Special, One Italian, and One Roast Beef with Roasted peppers and Provolone.
