Preheat the oven to 325 degrees F. Season the chicken on all sides with salt and arrange in a single layer in a baking pan. Evenly cover the chicken with the lemon juice, coriander, oregano, garlic, and olives. Drizzle the olive oil over all. Layer the lemon slices on top of the chicken. Place the baking pan in the oven and bake at 325 degrees F for 1 hour or until the chicken is cooked through. Serve with couscous, if desired.
