1) Using an apple cutter, slice apples.
2) Squeeze the juice from the fresh limes over the cut apples, or put the lime juice in a small bowl and dip both sides of the apple slices in the juice.
3) Put the slices into a container and they are ready for the lunch box. The fresh lime juice adds flavor and keeps the apple flesh white. Your kids will never throw away or give away their apples again!
