Blue cheese?

The "underground," secret grilled-cheese delivery guy has retired:

Ronnie," the out-of-work Wall Street banker who last summer started grilling the sandwiches in his East Village apartment and selling them on street corners, parlayed the health-code-violating gig into a real restaurant job.
"It was nice being an outlaw for a while," the secretive cheeseslinger told The Post. "But starting Monday, I will be the manager of a high-end American restaurant in Midtown."

Outlaw? Maybe if he had been delivering another kind of cheese...
