Wash and cut lettuce and dill. Peel cucumber and avocado and cut into small pieces. Serve salad on plates.
In a small bowl mix olive oil, apple cider vinegar, honey, lemon juice and salt and pepper. Drizzle on salad.
In a large pan heat avocado oil over medium heat. Add the flounder and cook for 1 minute each side or until fish is staring to flake. Season with salt, pepper and lemon juice.
Place the fish fillets onto a plate and add dill to 2 fillets. Place the remaining fillets on top and serve with the salad.
