In a medium bowl, mix together the olive oil, garlic, 2 tablespoons lime juice, chili powder, cumin, oregano, 1/2 teaspoon salt, and black pepper. Add the steak to the bowl and toss to coat. Marinate for at least 30 minutes.
Meanwhile, prepare the salsa. In a medium bowl, combine the mango, avocado, cilantro, red onion, jalapeno, 1 tablespoon lime juice, and 1/2 teaspoon salt. Mix until all ingredients are combined.
Heat a cast iron skillet or grill pan to medium-high heat. Add the steak and cook for 4-6 minutes per side, or until the steak is cooked to your desired level of doneness. Let the steak rest for 5 minutes before slicing.
To assemble the tacos, heat the tortillas in a dry skillet over medium heat. Top each tortilla with a few slices of steak, then top with the mango avocado salsa. Enjoy!
