OK, tried one in the name of science.  Got the “classic”. ( ketchup, mustard, chopped onions, and relish)

It will not blow your socks off, but for $1.99…  an acceptable snack.

My two teenage sons though give them a 10/10 and hammered out 8 of them.  Fair warning – teenage boys.  Their palates are somewhat… undiscerning.
