To prepare the dressing, whisk the olive oil, vinegar, mustard, lime juice, and honey together in a small glass or other non-reactive bowl. Season with salt and pepper, to taste. Taste and adjust seasonings, as desired. Set aside.
Wash and pat dry all vegetables before prepping. Toss Romaine lettuce, parsley, and basil in a medium bowl to combine. Divide all vegetables into 6 equal portions and set aside.
Divide dressing among the 6 mason jars. Add a layer of chopped cucumbers to each jar, followed by a layer of bell peppers. Next, add chickpeas and then the grape tomatoes. Top each jar with the lettuce-herb mixture and seal with a lid.
Store salads in the refrigerator until ready to serve. Each salad will last 4-5 days. To serve, remove from refrigerator and pour each jar into a salad bowl and enjoy!
