Oh, you'll get out of it with a whole plane, all right. It'll be right there, and there, and there, and some over there...

Basically, a snap roll is just a high speed stall. On most airplanes you do not need aileron to enter it; just give full up elevator at high speed (you need lots of elevator throw) and full rudder. The plane will snap in the direction of the rudder throw. Just release all controls and it should recover by itself.
