Mine would have to go to a sandwich I have been making for a couple of years now:
Start off with a good size focaccia bread (any flavor but I usually go with a rosemary and onion one) and slice it horizontally all the way across.
Next make a garlic aioli (mine is a tsp of salt, 1 egg white, a little bit of lemon juice, half cup of olive oil, 2 cloves of garlic pressed, and about 12 drops of yellow mustard)
Render down some bacon (the thicker cut the better) until desired crunch. Take excess bacon fat (2 tbsp) and add to aioli.
Take prepared chicken breast ( I pick mine up from a local market already prepared/breaded, but you can make whatever kind you like) and slice into 1 inch x 1/2 inch pieces
Take focaccia and add aioli to both sides, place into oven and cook on low broil until browned.
Slice granny smith apple, smoked gouda, dried cranberries and add on top of chicken. Add bacon and close. Eat like this or add to a panini press.
