To make the orange vinaigrette, grate orange zest into a glass jar. Cut orange in half and juice 1/2 of the orange into the glass jar. Add extra virgin olive oil, balsamic vinaigrette, honey and salt. Put the lid on the jar and shake to mix.
Add arugula to a bowl. Pour dressing over top of arugula and toss. Using a paring knife, remove the rind of the orange and cut it into slices. Arrange orange slices on top.
