Source: Bon Appétit Notes: I have never make the apple salad, though it sounds absolutely delicious and the perfect complement for such a sandwich. Also, I go with about 2 oz. of cheese per sandwich, though I can’t imagine 4 oz being so bad. Update: I now brown the bread a little differently thanks to a tip left by Trina — thank you! — in the comments. These changes apply to step 2. First, I spread one half of each slice of bread I with mayonnaise — it doesn’t burn as easily as butter, and the bread browns evenly every time. Second, instead of using butter in the pan, I use about a tablespoon of grapeseed oil — the high smoke point prevents it from burning. Butter, of course, works, but this is my preferred method these days.
