In a small bowl combine 2 tsp. flaky sea salt, 1 tsp. organic garlic powder, 1 tsp. organic onion powder, ¼ tsp. ginger powder, ¼ tsp. smoked paprika.
In another small bowl combine ½ cup coconut aminos, ½ cup sweet chili, 2 tbsp rice vinegar, 1 tsp garlic powder and 2 garlic cloves.
Place the 2 1/2 lb. flat iron steak in a shallow dish or tray. Rub both sides with the spice mixture you just made.
Place in the refrigerator and let rest 8 hours.
Remove 45 minutes before cooking and let rest on the counter.
Grease the grill grates and heat the grill to 425℉.
Place the steak on the preheated grill. After 2 minutes flip. Drizzle 1/4 of the sauce on top of the steak. After 2 minutes flip again and drizzle 1/4 sauce on top. You will use the other half of the sauce for the pasta. Cook another 2 minutes and flip. Do this so that each side gets a total of 4 minutes on the grill or until the internal temperature reaches a temperature of 135℉. It cooks fast, so you will want to keep a close eye.
Let rest 5 minutes before serving. Cut on a diagonal against the grain to serve.
