Prep the tuna: Pat tuna steaks dry and season lightly with salt and pepper.
Make the sauce: In a small bowl, combine soy sauce, sriracha, sesame oil, honey, garlic, and ginger. Adjust spice to taste.
Sear the tuna: Heat olive oil in a skillet over medium-high heat. Sear tuna 1–2 minutes per side for rare, 3–4 minutes per side for medium.
Add the sauce: Pour the spicy sauce over the tuna in the last 30 seconds of cooking to coat evenly.
Serve: Plate tuna, drizzle extra sauce on top, and garnish with green onions and sesame seeds. Serve with rice, salad, or steamed vegetables.
