In a large mixing bowl, combine the chopped romaine lettuce, diced heirloom tomatoes, and rinsed chickpeas.

In a separate bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, minced garlic, salt, and black pepper to create the dressing.

Pour the dressing over the salad and toss gently to combine.

Transfer the salad to a serving platter and sprinkle with crumbled feta cheese and chopped basil.
