Created for RSC #10. For a treat, try a strip of cooked bacon under the cheese before toasting.

Made this last night. Had some extra roasted chicken left over and wanted something quick and tasty to use it up. It was great. I didn't have any celery seeds, and can't eat raw onion so left that out, but otherwise followed recipe, putting half on one slice of bread and half on the other and eating them both open faced all by myself! The maple syrup and mustard made it so good! Thanks, Pamela!

Very good combination of ingredients for a nice hot sandwich. I quadrupled the amount of ingredients to make 3 large sandwiches (my buns were big!).

This was good. Was looking for away to use up some leftover cooked chicken breast. This was different and interesting looking. I misread the recipe and added 1 tbsp of dijon mustard, not sure if that is why I found the maple flavor non-existent and ended up using more maple syrup. Will try this again... with the right quantities. Used whole grain dijon mustard, subbed onion powder for the onion, and celery salt for the celery seed. Omitted the parsley, but like the suggestion of using italian seasoning. Tried it on a slice of bread and also on a pita (sort of like a pizza!). Baked in toaster oven for 12 minutes @ 400. Sprinkled red pepper flakes on top for a little kick.
