It's called Wondersauce. No, it's not ketchup and relish. It's a process. It has tomatillos and sugar (among other things). It originated in Texas and was meant to be more of a salsa than anything else. It's what makes the Wonderburger different from all our other burgers. This is the BIG WONDER featuring all the toppings of our traditional Wonderburger but amped up with Onion Rings and a half pound beef patty! 🍅❤️🐮
