Heat a grill for medium-high direct heat. Season the sirloin on all side with Salt Pepper + Three Chiles. Grill the steak over direct heat for 3 to 5 minutes per side or until it reaches about 127 degrees F. Set aside to rest for 5 minutes.

Meanwhile toast the tortillas and get your taco fixings ready.

Slice the bavette into thin pieces across the grain and then again into bite sized pieces. Build the tacos by laying down some avocado salsa, adding the beef, diced onions, cilantro, a big squeeze of lime, and your favorite hot sauce.
