Combine the chili powder, cumin, salt, pepper, paprika, corn/tapioca starch, garlic powder, onion powder, oregano, sugar, red pepper flakes, and cayenne pepper in a glass jar with lid. Cover the jar and shake to combine.
For tacos:
Cook beef or turkey and onion in a large skillet over medium heat for about 10 minutes, stirring occasionally, until meat is brown; drain. Stir in the black beans, 1-2 tablespoons of taco seasoning (to your taste), and ⅓ cup water. Simmer until the water has mostly evaporated, about 10 minutes.
Place meat and bean mixture in tortillas/taco shells and top with your choice of toppings. Enjoy!
