On a cutting board, place a slice of ham and slice it in half lengthwise.
Place an apple slice on top of the ham, on one end, and a thin slice of cheese on top of the apple slice.
Beginning by the apple end, roll the apple and cheese slices onto themselves to wrap them with the ham.
For a packed lunch:
Place each ham and cheese wrapped apple slice inside a bento box or lunch container. In a separate compartment, add fruit, veggies, crackers, or the sides of your choice.
Notes
To keep the apples from browning, brush the slices with lemon juice after coring and slicing.
