Completos: An anorexic's nightmare

Tonight I had my first experience with a Chilean completo.  It's an anorexic's nightmare:  it consists of a hot dog in an oversized bun topped with tomatoes, thinly sliced onions, mashed avocados, mayonnaise, ketchup, mustard and more salt than the Pacific Ocean.  It was delicious!  Completos come in different variations, and they can be found all over the city.  One completo is enough to feed a small African village, and yet I was able to eat two tonight.  This is one recipe I will definitely be bringing back to the US withe me!
