For the Apple - With the skin still on, cut the apple in half from the top to the bottom of the apple. Then cut each half into slices (around the core) that are about ¼ of an inch thick. Set aside.
For the Wrap - Lay the wrap on a large cutting board or plate and spread the mayonnaise and mustard on the wrap.
Add the ham, kind of “fluffing” it up rather than laying it flat. Sprinkle pepper on top of the ham.
Top the ham with a layer of apple slices, crumbled blue cheese, spinach and onions.
Gently fold the right and left sides of the wrap inwards about 1-1/2 inches on each side.
Roll the wrap starting with the end closest to you towards the other end like you would a burrito.
Cut in half on a diagonal. Serve alone or with soup or salad.
