Combine taco seasoning spices in a small bowl, and set aside.
Make the taco meat: Add ground beef to a large skillet or cast-iron pan. Cook, crumbling into small pieces with a wooden spoon, until browned. Add spices and stir well to combine. Stir in black beans. Keep on low heat while you fry the tortillas.
Crunchy tortilla shells: Fill a medium pot or skillet with enough oil to fill about 1-inch up the sides. Heat oil to 325 degrees F. Once hot, use tongs to dip one half of the tortilla into the oil, laying it flat, while folding the other end over (but out of the oil, to create a “U” or “taco shell” shape. Cook for about 1 minute, until golden and crisp, then flip and repeat with the other side of the tortilla, until crisp. Remove to a paper towel lined plate, and repeat with remaining tortillas.
Serve: Add a big spoonful of ground beef mixture into each taco shell. Top with lettuce, tomato, cheese, sour cream, salsa or other desired toppings. Serve with a side of Mexican rice.
