In a small bowl, whisk together the olive oil, lemon juice, honey, oregano, garlic powder, black pepper, and salt to create a dressing.
In a large mixing bowl, combine the black beans, red bell pepper, cucumber, cherry tomatoes, onion, and cooked chicken breast.
Pour the dressing over the salad mixture and toss everything together until well coated.
Serve the salad on a bed of romaine lettuce and sprinkle with feta cheese.
