If you are making your own pita chips, please refer to the notes above for instructions. If you have purchased pre-made pita chips, proceed to step 2.
In a large bowl, combine the halved cherry tomatoes and cucumber chunks.
Add in the chopped green onions, parsley, and mint to the tomato and cucumber mixture.
In a separate bowl, whisk together the olive oil, lemon juice, grated lemon rind, minced garlic, salt and pepper to create the dressing.
Pour the dressing over the tomato and cucumber mixture and toss to combine. Cover and let marinate in the refrigerator for at least 30 minutes to 3 hours.
To serve, place the torn romaine lettuce in a serving dish and add the marinated tomato, cucumber mixture and pita chips. Toss to evenly distribute the dressing.
