How to Make It
Heat 1 tablespoon of the oil in a large skillet over medium-high heat. Add the ham and cook until crisp, 5 to 7 minutes.
In a large bowl, toss the orange segments with the orange juice, vinegar, the remaining oil, ¾ teaspoon salt, and ¼ teaspoon pepper. Add the arugula, onion, and ham and toss to coat.
