In a large bowl, add the black eyed peas, corn, carrots, red onion, tomatoes, greens, and parsley.
In a pint sized mason jar (or other airtight container), add all the dressing ingredients: olive oil, apple cider vinegar, maple syrup or raw honey, mustard, and salt and pepper to taste. Seal the jar with an airtight lid, and shake the ingredients well for a few minutes until dressing is well combined.
Pour dressing on the salad right before serving, and toss well. Enjoy!
