WHAT is on the salad in Mexico?

[newholidayx2]

There was definately something very hot/spicy on the salad at lunchtime in San Angel. Could it have been the dressing? and what exactly was it?

Most likely some chiles in the dressing. The menu doesn't show anything else that would be spicy: Ensalada Mexicana - mixed greens with grilled chicken, tomatoes, avocado, sweet Mexican turnip, cheese and cactus strips, tossed in our house dressing and served in a fried tortilla shell $10.75
