What's the biggest food challenge a sandwich fan can take on? Two years ago, Chicago-based systems engineer Jim Behymer and his group of sandwich-loving friends on Twitter were ruing the very idea when Behymer shot out a random suggestion on the social networking site: Let’s pig out on all the sandwiches mentioned on the Wikipedia list.

The idea met immediate approval from his Twitter companions Josh Augustine and Thom Robinson — both self-proclaimed foodies. Just that, they had over 185 sandwiches to dig into. “And we were just three,” he says. The trio decided to take it really slow, making it their “five-year mission” to cover everything on the list. That’s how the Sandwich Tribunal — a blog dedicated to world sandwiches — was born. “We are currently in the 22nd month of working the list, and at three sandwiches a month, we have covered 66 sandwiches till date,” says Behymer, in an email interview. With five more writers joining this sandwich-eating trio’s exercise in gluttony, this mission couldn’t have been more fun, he adds.
