Whisk the dressing ingredients together in a small bowl until fully emulsified. Set aside. The dressing should be stored separately and added just before serving.
In a large wide mouth jar, layer the ingredients in the following order: chickpeas, cucumbers, cheese, tomatoes, olives, gently packed lettuce, and red onion.
To serve, pour the dressing into the jar, secure the lid tightly, and shake until evenly coated. Alternatively, empty the jar into a serving bowl and toss with the dressing to combine.
