The meat at Subway is Tofu?

I met this girl recently who claimed to formerly work at Subway. She also claimed that Subway couldn't afford real meat so they use Tofu. And that all of the veggies are pre-packaged and not fresh at all. I knew that the veggies aren't fresh because I've seen an employee getting them out of packages. But is the Tofu thing real? I usually get a veggie sub anyway... but I wondered about it none the less.
