Several things can be modified to taste. Waffles can be store bought or homemade, cooked chicken meat bits can be incorporated to the homemade waffle mix as well The chicken can be cooked to user preference, be it cooked on the griddler or via sous vide then fried etc. Left over chicken from a previous meal is best. The inspiration for this sandwich was out of necessity. One day I found myself coming home from work and all I had in the freezer was some waffles and some left-over chicken in the fridge. I figured what the heck, and used a grilled cheese maker I had (this was before I had the pleasure of working with a griddler deluxe) The sauce was a mixture of ketchup and maple syrup, not knowing how it would taste it was first used as a dipping sauce for the sandwich. Later versions it has been incorporated into the sandwich.
