The chicken patties have always been suspect, but as someone who in my youth worked at a Subway for about 3 years, and managed it for a few months of those, I can assure everyone....the Tuna is very much real tuna. The giant heavy cans and the smell are still burned into my brain, and nothing has changed - I occasionally deliver to the foodservice that supplies Subway and rest assured, the cans of tuna are still very much tuna. It's simply mixed with mayo in the store until it's the right consistency, and that's it.
The people who filed that lawsuit are off their rockers.
