Combine the lentils, water and salt in a pot, and bring to a boil. Once boiling, cover and reduce the heat to low. Simmer for 35-40 minutes or until the water is absorbed.
While the lentils cook, combine the Greek yogurt, dill, lemon juice and honey in a small bowl. Stir with a spoon, and set aside.
When the lentils are cooked, place them in a large bowl. Top with cucumber, tomatoes, red onion, chickpeas, feta and Greek yogurt dressing. Season with salt and pepper.
