You can take most ordinary salads and add any or many of the following, and they become really tasty:
-cheese: feta, blue, oka, brie (heated to melty in microwave), even plain old old cheddar
-raisins
-croutons made from sourdough bread, or pumpernickel is good, too
-red onion, thinly sliced and sauteed in olive oil
-fruit like apples, pears, oranges (mandarin especially good) avocados
