Tomato Conspiracy

When you go to Italian restaurants like the Olive Garden or Maggiano’s, they serve you these huge salads with literally two or three tiny tomato slices.  Not two or three tomatoes, two or three slices, for the entire salad.

How is it that Italian restaurants, establishments that owe their very existence to the power of the tomato (in sauce form), are so consistently skimpy when it comes to tomatoes in salad?
