In a large jug or bowl, whisk together the olive oil, lemon juice, water, red wine vinegar, parsley, dried basil, minced garlic, dried oregano, salt, and pepper. Divide the mixture in half - pour one half into a shallow dish for marinating the chicken, and refrigerate the other half to use as dressing later.

Add the chicken to the marinade in the shallow dish, ensuring all pieces are well coated. Let it marinate for 15-30 minutes at room temperature, or up to two hours in the refrigerator if you have time.

While the chicken is marinating, prepare all the salad ingredients. In a large salad bowl, combine the lettuce, diced cucumber, diced tomatoes, sliced red onion, sliced avocado, and olives if using. Set aside.

Heat 1 tablespoon of olive oil in a grill pan or on a grill plate over medium-high heat. Remove the chicken from the marinade (discard the used marinade) and grill for 5-7 minutes per side, or until browned and completely cooked through. The internal temperature should reach 165°F (74°C).

Remove the cooked chicken from the heat and let it rest for 5 minutes before slicing. This helps keep the juices in the meat.

Arrange the sliced chicken on top of the prepared salad. Drizzle with the reserved (unused) dressing. If using feta cheese, sprinkle it on top. Serve with lemon wedges on the side for an extra burst of freshness.
