Aurora Guerrero came up with the recipe for Cielito Lindo's famous taquitos with green avocado sauce when this venerable stand opened in the 1930's. The dish she created features a dab of guacamole inside a meat taquito and a green sauce that is like salsa verde plus avocado. It is definitely an affordable and tasty treat! This food stand is a great meal stop if you are in the Olvera Street area and want some authentic Los Angeles street food.
