Fry the hamburger meat in small amount of oil, with the flour and salt stirred in. Warm the tortillas if they break when handled. They can be wrapped in a cloth and warmed in a very low oven a few minutes. Or they can be fried enough to warm them in hot oil. Don't fry them crisp or they can't be folded. Spoon the hamburger on the tortillas and fold over. Fill the tortilla with shredded lettuce, onions, and radishes. Sprinkle grated cheese on top of the lettuce and the amount of sauce desired. A few drops of hot pepper sauce may also be added. Close the taco and serve while hot.
Taco Sauce: Heat the tomato puree, oregano, 3 tablespoons chili, oil, and a little water if necessary. Simmer a few minutes, stirring while it heats. The hot pepper sauce can be added to this sauce or each person can add to the filled taco, as he desires.
