Arby's just started testing a new sandwich called the ARBYNATOR, that features roast beef, cheddar cheese sauce, and curly fries all on a bun.

For now, they've only been spotted in Holland, Michigan . . . so there's no word on when they could go nationwide.  But again, if you REALLY want one now, you can assemble one yourself with like three seconds of work.

Thanks to GrubGrade reader Bryce who sent over a picture of new Arbynator sandwiches from Arby's. The new menu item was spotted at an Arby's in Holland, Michigan. From what I can tell from the menu board pic, the Arbynator is a roast beef sandwich topped with Curly Fries, cheddar cheese sauce, Red Ranch, and possibly mayo?
