Turkey, Apple, and Brie Sandwich with Apple Cider Mayo

loaf good quality, pre-sliced french sandwich bread

granny smith apples

of Brie cheese, sliced into thin strips (I like to remove the rind that is on the top and bottom of the cheese, just so you aren't getting too much of it. This way the rind will only be around the edge)

apple cider vinegar

mayonnaise

Arugula
