- 1/2 cup sesame seeds (white, black, or a mixture)

To make the dressing, combine the vinegar, soy sauce, olive oil, scallion, ginger and red pepper flakes in a liquid measuring cup. Whisk well to blend.

Season the tuna steaks with salt and pepper on both sides. Place the sesame seeds in a pie plate or shallow dish and, working with one piece of fish at a time, press the tuna into the seeds to adhere to all sides. Heat the grape seed oil in a non-stick pan over high heat. Once the pan is hot, add the portions of tuna to the pan. Cook for 45-60 seconds on one side, flip and do the same on the second side. Use tongs to stand the pieces up and sear the sides for about 30 seconds. Remove to a cutting board and slice thinly.

In a large bowl, combine the greens with a few tablespoons of the vinaigrette and toss until evenly coated. Taste and add more dressing if desired. Portion the greens out onto serving plates and top with the sliced avocado and radish. Lay each portion of sliced tuna on top of the bed of greens and serve immediately.

- Bibb lettuce would be another excellent option for part of the greens, though it isn’t currently in season.
- If you can’t find watermelon radish, consider topping with thinly shaved red bell pepper and grated carrot in its place to add additional pops of color and texture.
