Method
In a medium mixing bowl, whisk together the soy sauce, sesame oil, rice vinegar, honey, and sriracha (if using) until well combined.
Add the cubed ahi tuna to the bowl and gently toss to coat the fish evenly with the marinade. Be careful not to break up the tuna cubes.
Stir in the chopped jalapeño, sliced green onions, toasted sesame seeds, and chopped cilantro, ensuring all ingredients are evenly distributed.
Cover the bowl with plastic wrap and refrigerate for at least 15 minutes to allow the flavors to meld.
Remove the bowl from the refrigerator and give the poke a final gentle stir before serving.
