That is what the local delis call a sandwich similar to this so that is what I'm calling it too.
Store had split chicken breasts on sale for $0.99/lb. Deboned 3 split breasts and chopped them up in the food processor. placed the chicken in a ziplock bad and added about half cup Italian dressing and let it marinade for about an hour.
Took enough chicken for a sandwich and spread it on the griddle
Just before flipping I added some seasoning and some chopped onion.
Cooked until chicken and onion were done, also warmed up a bollio roll
Loaded up the roll
and added provolone cheese and then took them off the grill when the cheese was melted.
