What garnish is commonly found in the San Francisco Benedict that distinguishes it from other benedict options?

The San Francisco Benedict is typically distinguished from other Benedict variations by the inclusion of avocado. This unique ingredient not only adds a creamy texture but also brings a rich, buttery flavor that complements the dish's other components, such as poached eggs and hollandaise sauce. The use of avocado reflects the culinary trends of the San Francisco area, where fresh and healthy ingredients are often prioritized.

In contrast, while mushrooms, onions, and peppers can be components in various other dishes or even other benedict styles, they do not provide the same defining characteristic that avocado does for the San Francisco Benedict. The focus on avocado marks this variation as both unique and trendy, aligning with the region's emphasis on incorporating fresh produce into meals.
