Thanks to shambo & Ginger for the recipes (and thanks for the new website with lots of nice recipes).

Hope it tastes just like the real thing.

Ginger, I made the recipe from that sotbox website, added an extra tsp of fresh lime juice and sprinkled a bit more cumin and minced cilantro and it was excellent! Just made another batch of it tonight. My DH loves it too. There are no El Pollo Loco's on the Eastern side of the USA so I'm very glad to have this dressing. thanks again! Ann

Wow, this is an old request-2007. I love almost everything on El Pollo Loco's menu. I believe it has got to be some of the tastiest, healthiest fast-food available. Their Creamy Cilantro Dressing is their most popular; it's one of the tastiest, creamiest salad dressing recipes ever created. I recently found and tested this version of El Pollo Loco Creamy Cilantro Dressing, and found it to be truer to the original dressing than the previous recipe posted. I discovered it at the meemoskitchen link included below. Enjoy!
