Creating this delightful Spicy Tuna Salad is straightforward if you follow these simple steps:

1. Prep Ingredients: Begin by draining the tuna thoroughly. This prevents excess moisture in the salad.

2. Mix Base Ingredients: In a medium bowl, add the drained tuna, mayonnaise, Sriracha sauce, soy sauce, and lemon juice. Mix until well combined.

3. Add Veggies: Gently fold in the diced cucumber, chopped celery, and red onion. Ensure all vegetables are evenly distributed.

4. Season: Taste the mixture and add salt and pepper to your preference.

5. Chill (Optional): For enhanced flavors, cover the bowl with plastic wrap and place it in the refrigerator for about 10 minutes.

6. Serve: To plate, spoon the salad onto fresh lettuce leaves if desired. Garnish with chopped green onions for a pop of color and flavor.

7. Enjoy: Dig in right away, or store any leftovers in an airtight container in the fridge for up to two days.
