You may have laughed at the redundancies of chai tea, prosciutto ham, shrimp scampi, where the English word means the same thing as the foreign word it is paired with.
A couple days ago I saw one new to me: cheese quesadilla. Quesadilla literally means "little cheesy thing". See http://en.wikipedia.org/wiki/Quesadilla.
