Carne Asada Tacos

These are simple tacos which are sold by street vendors in Mexico.

16 corn tortillas
1/2 cup onion, diced
1/2 cup cilantro leaves, chopped
8 squares aluminum foil
2-3 tablespoons vegetable oil
Salt to taste

Heat oil in a medium pan over high heat. Cook the beef until the edges become browned and crispy. Add salt to taste.
