Preheat the broiler.
Toss the chicken in a large bowl with 1/4 cup of the Greek Feta Herb Vinaigrette and sprinkle with salt and pepper. Set aside while you assemble the salad.
Lay the romaine on a large deep platter (or 4 wide, shallow bowls). Top with the tomatoes, bell pepper, cucumbers and olives.
Arrange the chicken on a baking sheet and broil, turning once, until browned and cooked through, about 8 minutes per side. Let the chicken cool for a few minutes and then slice.
Serve the warm chicken on the salad. Sprinkle with the pita chips and feta. Drizzle with the remaining vinaigrette.
