In a large glass or ceramic mixing bowl, sprinkle some kosher salt and rub the sides with the garlic. Discard the garlic.
Place the lettuce, radishes, onion, scallions, green pepper and tomatoes in the bowl. Add the oregano, dill and mint.
Just before serving, add the olive oil and vinegar. Season with salt and pepper. Toss to coat.
Sprinkle the feta/ goat cheese over the salad and arrange the olives on top. Serve right away.
