It's clearly two sandwichs.
The bold move would be to have the other side have the peanut butter and jelly swapped around. I'd call that the ouroboroswich.
[edit] what if it only had 1 cut? I think that'd be a taco
[edit 2] a torus cut once makes a cylinder. So really, it's a double decker sandwich
[edit 3] but it's cylinders that loop back on themselves. Is it a mobiuswhich or a Klien Wich?
[edit n] help
