Ingredients

Tuna Filling

2 cans tuna in water 12 oz or 340g, drained
¼ cup mayonnaise 60 ml
1 tbsp sriracha sauce 15 ml
1 tsp soy sauce gluten-free if necessary, 5 ml
½ avocado diced, 100g
¼ cup red onion finely chopped, 40g
1 tbsp fresh cilantro chopped, 4g

Seaweed Shells

8 large seaweed sheets (nori)

Toppings (optional)

¼ cup shredded cabbage 35g
jalapeño thinly sliced
lime wedges for squeezing
sesame seeds for garnish

Instructions

Begin by preparing your tuna filling. In a medium mixing bowl, combine the drained tuna, mayonnaise, sriracha sauce, and soy sauce. Stir until the ingredients are well mixed and the tuna is coated evenly.
Add the diced avocado, chopped red onion, and fresh cilantro to the tuna mixture. Gently fold these ingredients into the tuna to distribute them throughout without smashing the avocado pieces.
Lay a seaweed sheet flat on a clean surface. Place an even amount of the spicy tuna mixture onto one end of the seaweed sheet.
If desired, add your additional toppings such as shredded cabbage and jalapeño slices on top of the tuna mixture.
Carefully roll the seaweed sheet around the filling, starting from the end with the tuna, to form a taco shell shape. The moisture from the filling will help seal the seaweed. Repeat with the remaining seaweed sheets and filling.
Serve immediately with lime wedges for squeezing and a sprinkle of sesame seeds for garnish.

Notes

For those who prefer less heat, reduce the amount of sriracha sauce or replace it with a milder hot sauce.

Ensure your soy sauce is gluten-free if you are adhering to a gluten-free keto diet.

The seaweed shells are best enjoyed immediately after assembly to maintain their crispness.

If you're preparing this for a party, you can make the tuna filling ahead of time and refrigerate it, then assemble the tacos just before serving.
