Step 1

Add the beef to a large skillet over medium-high heat. Break the meat apart with a wooden spoon. Add the chili powder, cumin, salt, oregano, garlic powder, and pepper to the meat. Stir well. Cook until the meat is cooked through, about 6-8 minutes, stirring occasionally.

Step 2

Reduce the heat to medium. Add the tomato sauce and water. Stir to combine. Cook, stirring occasionally, for 7-8 minutes, until some of the liquid evaporates but the meat mixture is still a little saucy. Remove from the heat.

Step 3

Warm the taco shells according to their package directions.

Step 4

Fill the taco shells with 2 heaping tablespoons of taco meat. Top with desired taco toppings: shredded cheese, shredded lettuce, chopped tomatoes, diced red onion, taco sauce, sour cream, guacamole, etc.
