Step 1
Cut the apple into 1/4-inch-thick slices. Dip the slices in the juice to coat each side (this prevents the apple from browning). Shake off the excess juice.
Step 2
In a small bowl, blend the peanut butter and honey together. Spread half the slices with the peanut-butter-and-honey mixture; then top with a second slice.
Step 3
Seal with plastic wrap and keep chilled until ready to eat.
