Pat the tuna steak dry and season both sides with a pinch of salt and black pepper.
Heat a skillet over medium-high heat and add sesame oil. Sear the tuna steak for 1-2 minutes on each side for medium-rare, or adjust to your desired doneness. Remove from skillet and let it rest for a few minutes before dicing into small cubes.
In a small bowl, mix the mayonnaise, sriracha, soy sauce, lime juice, and chili flakes to create a spicy mayo sauce. Adjust sriracha to your spice preference.
Slice the avocado in half, remove the pit, and cube the flesh. Slice the cucumber into thin half-moons. Chop the green onion into fine pieces.
In a mixing bowl, combine the diced tuna, avocado cubes, cucumber, and green onion. Drizzle the spicy mayo sauce over the ingredients and gently toss to coat evenly.
Serve the keto spicy tuna in a bowl, sprinkle with sesame seeds for garnish, and serve with a side of seaweed sheets (if using) for scooping. Enjoy immediately!
