Start by preparing the tuna steaks. Pat them dry with paper towels to remove moisture, then season with a pinch of sea salt and black pepper on both sides.
In a shallow dish, combine the sesame seeds. Press each tuna steak into the sesame seeds, coating all sides evenly.
Heat the sesame oil in a non-stick skillet over medium-high heat. Once hot, sear the tuna steaks for about 1-2 minutes on each side for rare, or cook longer to your desired doneness. Remove from the skillet and let rest before slicing.
While the tuna is resting, prepare the base for the bowls: in a bowl, layer the cooked brown rice or quinoa.
Add edamame, sliced avocado, cucumber, and radish artfully on one side of the bowl.
Slice the seared tuna into thin strips and place them on top of the rice or quinoa.
Drizzle soy sauce and honey over the tuna and the entire bowl for added flavor.
Garnish with chopped green onions and microgreens, if using. Serve with pickled ginger on the side for a zesty touch.
Notes
Use fresh sushi-grade tuna for the best flavor and texture.
