In a bowl, mix together the coconut aminos, lemon juice, Worcestershire sauce, dried basil, and garlic powder.
Add the steak to the bowl and turn it to coat evenly. Let it marinate for at least 30 minutes.
Heat a skillet over medium-high heat. Sear the steak on both sides until it reaches your preferred level of doneness.
Remove the steak from the pan and let it rest for about 10 minutes.
Slice the steak thinly against the grain.
Divide the greens among four plates. Top each with sliced steak, tomato, mozzarella, and a light drizzle of balsamic vinegar.
Serve immediately.
