"I almost never use olive oil for anything because its flavor overtakes everything. "
That depends on the type of olive oil.
Extra Virgin Olive Oil, or EVOO as Rachel Ray called it, is by far the most flavorful, and generally the most expensive. It's from the first press of the olives.
As further pressings extract more oil, the flavor becomes more and more neutral, to the point where light/extra light olive oil is almost as flavorless as straight vegetable oil.
