Instructions
Whisk together soy sauce, mirin, sesame oil, ginger, garlic, and honey in a small bowl to create the glaze.
Pat tuna steaks dry and season lightly with salt and pepper.
Heat a non-stick skillet or cast-iron pan over medium-high heat with 1 tsp oil.
Sear tuna for 1–2 minutes per side for medium-rare (longer if desired). Remove and let rest.
In the same pan, add spinach and cook briefly until wilted (30–60 seconds). Season lightly with salt and a drizzle of sesame oil.
Slice tuna against the grain and drizzle with the ginger-soy glaze. Serve on a bed of sesame spinach, sprinkled with sesame seeds and a squeeze of lemon.
