I've seen this recipe on several websites, but this one is from the health.com website. The ingredients are largely from fresh Pacific NW produce from the Pike Place Market. Most people associate Pike Place Market with its brief spot in the limelight in the Tom Hanks/Meg Ryan movie "Sleepless in Seattle" that was filmed in Seattle, or for the entertaining "fish tossers" at the fresh fish stand. But it's so much more than that. Pike Place Market is truly a must-see for anyone visiting Seattle with stand after stand of fresh fish caught in the Pacific Northwest waters, locally grown fresh produce, and a plethora of intriguing and quaint boutiques selling local artisan's crafts and wares. Be sure to visit the Pike Place Market whenever you make a stop in Seattle. NOTE: The recipe calls for pre-bagged herb salad mix. If you cannot find it at a your local market, just use any combination of lettuces and herbs.
