Recipe: Mix the ingredients for the marinade and pour it in a zipper bag. Put the tuna steak inside and close the bag. Keep the bag with the tuna at room temperature for 40 minutes, turning it 2-3 times. Grease lightly a cast iron pan and flash-sear the tuna steak on all sides until rare. Prepare the sweet sesame ginger dressing and mix little wasabi sauce in it. Slice the seared tuna steak to 1/8-inch horizontal slices and serve it with your favorite salad mix. Drizzle the sweet wasabi ginger dressing over the tuna steak. You can sprinkle with toasted sesame seeds for decoration. Serve the tuna immediately.
