In a small bowl, mix together all the taco seasoning spices. Set aside.
2 teaspoons chili powder, 2 teaspoons cumin, ½ teaspoon oregano, ½ teaspoon garlic powder, ½ teaspoon salt, ½ teaspoon black pepper
In a large skillet, heat the olive oil over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon or spatula, until browned and no longer pink, about 5-7 minutes. Drain any excess fat from the skillet.
