Combine in med sized bowl: soy sauce, sesame oil, honey, rice vinegar, ginger, garlic, juice of 1 lime. Whisk together. Add salt & pepper to taste. If you want it a little spicy, add about 1/2 tsp red pepper fakes.
In large zip lock baggie, add ahi tuna steak. Pour in 1/4 cup dressing. Marinate for 30 minutes (or up to a couple hours). Reserve remaining dressing to use as salad dressing.
Prepare salad. Layer lettuce on platter or shallow bowl, top with grated carrots, thinly sliced bell peppers, sliced cucumber, broccoli cole slaw mix, and cubed avocado.
In cast iron skillet over medium heat, heat pan and add coconut oil. Remove ahi tuna steak from marinade (pat or shake off excess marinade), and cook for approximately 3-5 minutes per side. Cooking time will depend on thickness of ahi steak and how rare you want it. I cooked mine for about 7 minutes total.
Thinly slice ahi tuna steak and place onto salad. Drizzle with the remainder of Ginger Sesame Dressing (or to your liking), then top with a sprinkle of sesame seeds and a squeeze of lime.
Enjoy!
