Combine chicken with all ingredients except tomatoes, lettuce and dressing. Chill. Remove stem ends from tomatoes. Cut from top about 3/4 of the way down each tomato in about 8 pieces. Spread tomatoes open on shredded lettuce or lettuce leaf. Fill with salad mixture and top with Avocado Dressing. Dressing: Place all ingredients in blender container. Blend until smooth. Chill. (If prepared well ahead of serving time, place avocado seed in dressing to prevent turning dark).
