1. To a large zip lock bag add soy sauce, lime juice, orange juice, avocado oil, coconut sugar, cumin, garlic powder, smoked paprika, chili powder, onion powder, oregano, and salt. Whisk to combine ingredients. Add steak to the bag and squeeze out any air. Marinate in the refrigerator for 2-12 hours.
4. Remove steak from marinade and discard bag. Add steak to the grill and cook each side 7-10 minutes flipping once for medium steak. Add an additional 5 minutes for a medium-well steak. If you like rare steak cook on HIGH to get a nice char on the outside in less time.
