Add all ingredients for the dressing to a mason jar. Secure with lid and ring and shake - shake - shake. Place in refrigerator until ready to add to salad.
In a bowl, add beans, onion, bell pepper and arugula. Toss to combine. Shake dressing very well then pour over veggies. Sprinkle in goat cheese and gently fold to combine (do not stir too hard, the cheese will break up too much). Cover and place in refrigerator until ready to serve. (up to 24 hours)
