I think that’s a Cuban Reuben. One of the substitutions is cole slaw.
In fact, I like the turkey in place of the pastrami. Don’t mind mammal meat, but turkey is less gristly to eat thru. Rather have it smooth.
The other thing is most sub 1000 Island for Russian dressing. Not terrible, but not fully accurate. I guess Russian is not common so they wing it.
I use thousand island myself when making them at home. Never cole slaw, though, no matter what.
