Place mixed greens in the bottom of a 2-1/2-quart clear salad bowl. Layer in the following order: garbanzo beans, tomatoes, sliced fennel or celery, sweet peppers, turkey ham, and green onions.
For dressing, stir together mayonnaise or salad dressing, milk, snipped fennel tops or fennel seed, and white pepper. Spread the dressing over the top of the salad, sealing to the edge of the bowl. Cover tightly with plastic wrap. Chill for 4 to 24 hours.
Before serving, top salad with cheese; toss gently to mix. Makes 10 side-dish servings.
