Drop the shrimp into boiling water flavored witha little salt and lime juice. Cook til just pink, usually 1-2 minute Drain and cool slightly; shell and devein. Place in a bowl; cover with plastic wrap and chill.
Arrange lettuce leaves to cover two large dinner plates (at Joe's, this is made on large oval plate). Place a mound of shrimp on one side and a mound of garbanzo beans on the other. Place tomato slices in the four "corners" of the plate. Cut the eggs lengthwise in quarters and place a quarter next to each tomato slice. Place a lemon half at the end of each plate and 2 olives at the top and bottom. Place the green pepper rings at the edges. Cover and chill if not serving immediately.
To make the Louis dressing:
Combine the mayonnaise, chili sauce, grated onion, parsley, salt, black pepper, cream, Worcestershire sauce, and Tabasco sauce. Stir until blended. Chill, covered, until serving time. If too thick, stir in a little more cream. Serve dressing in a small sauce-boat beside the shrimp.
This is a good-looking plate. The Louis dressing can be used for other cold seafood, too. Louis dressing contains a large amount of mayonnaise, but is not a problem if used as a dip. Don't eat it like soup!
