Another variation adds one extra step. Just before assembling the salad, quickly saute with a little olive oil the cooked and drained lentils, the chopped vegetables (not including the feta or sauce), and the sliced cooked chicken. Add a squeeze of fresh lemon juice and adjust seasonings. Then assemble the dish with the feta and sauce. Not a necessary step but it is another way of presenting this dish. Ohhhh so good!
