Prepare dressing: Place all of the ingredients in a high speed blender or food processor. Puree until smooth. Add a little more water, if necessary, to reach the desired consistency. Taste and adjust seasonings, if needed. Refrigerate until ready to use.
To assemble salads: Divide the baby lettuce mix between six large dinner plates, or in a very large, shallow bowl. Top with the remaining ingredients. Serve with the dressing on the side.
Notes
