Garden Salad with Dungeness Crabs

I was looking for the easiest recipe for garden salad with crab meat the other day. I found this recipe ( Food network) called the New Orleans Style. However, this is similar to my wife's recipe of Crab Louie salad.
My wife has the same recipe without the green onions and the olives.( a much simpler recipe)

1 head iceberg lettuce, cored and cubed
1 pound lump crabmeat, picked over for shells and cartilage(Dungeness preferred)
1/2 cup chopped yellow onions
1/2 cup chopped celery
1/2 cup roughly chopped pimiento-stuffed green olives (about 8 large)
2 tablespoons chopped green onions
2 tablespoons chopped parsley
2/3 cup olive oil
1/3 cup red wine vinegar
1 teaspoon minced garlic
1/2 teaspoon salt
1/4 teaspoon freshly ground black pepper

In a large bowl, combine the lettuce, crabmeat, onions, celery, olives, green onions, and parsley. In a small bowl, combine the oil, vinegar, garlic, salt, and pepper, and whisk to blend. Pour over the crabmeat mixture. Toss gently to coat, being careful to not to break up the crabmeat lumps. Adjust seasoning, to taste.

Refrigerate until well chilled and the crabmeat is marinated, at least 2 hours. Serve.
