Tacos with Ground Meat (Tacos con Carne Molida)

Heat shortening in a heavy skillet, brown the meat with the green pepper and onion until onion is transparent, pepper is soft, and the meat nearly cooked through. Add the potato, tomatoes, sugar, chili powder, coriander, salt, and pepper and stir to blend, cooking a few minutes more. Mix in the olives. Cook for about 10 more minutes, stirring constantly. Heat the tortillas to soften them, play some money on each tortilla, spread it out, roll the tortilla, and fasten with toothpicks. Fry in hot oil until crisp. Serve lettuce and tomatoes which have been drenched in your favorite oil and vinegar dressing. Add other garnishes, if you like.
