Place arugula (or spinach) in a bowl. Place remaining ingredients on top and gently toss.
In a smaller bowl, whisk all of the ingredients together except for olive oil. Slowly pour in olive oil while whisking to emulsify. Toss dressing with salad and enjoy!
*Let yogurt sit out for about an hour. It's much thinner and more easily able to be poured. Make ahead: You can make this salad ahead of time, but I wouldn't definitely keep the dressing on the side to prevent wilting. Toss with dressing just before serving.
