I make this very rarely, maybe once or twice a month, and I hate the WF dressings. I use the lowest carb real thousand island, put the chopped lettuce in a bowl, a about 1tbsp thousand island (mine gives me just 2.5g carbs), add a little apple cider vinegar (just a splash) to thin out the dressing a touch (although you could just stretch it with WF and boost the WF dressing flavor too), and toss it really well. Then I put the other ingredients over that. I have added just a 1/2 ounces of shredded zero carb, low fat cheese in the past too.
Mine never looked as pretty as Steve's does!
