Ingredients and Simple Swaps

• 10.5 oz canned tuna, drained (300 grams, drained weight approx. 14-15 oz / 400-450 gram can)
• ⅓ cup green onion, chopped (plus extra for garnish)
• ⅔ cup diced cucumber
• ⅔ cup diced red bell pepper
• ⅔ cup diced celery
• 1 tablespoon light soy sauce
• 2 teaspoons rice wine vinegar or lemon juice
• 1 teaspoon sesame oil
• ¼ cup light mayonnaise
• 2 tablespoon Sriracha chili sauce (plus extra to drizzle)
• 4 nori seaweed sheets (cut into quarters, 4-6 sheets)
• 2 tablespoons toasted sesame seeds (for garnish)

Assemble the Bites

1. Dice green onion, cucumber, red bell pepper, and celery into small cubes.
2. Drain the canned tuna and place it in a mixing bowl.
3. Add light mayonnaise, Sriracha, light soy sauce, rice vinegar or lemon juice, and sesame oil to the tuna.
4. Stir everything together until well combined.
5. Fold the diced vegetables and chopped green onion into the tuna mixture.
6. Cut nori sheets into bite-sized squares using kitchen scissors.
7. Scoop about 1–2 tablespoons of tuna mixture onto each nori square.

8. Sprinkle toasted sesame seeds and extra chopped green onion over each bite.

   

9. Drizzle additional Sriracha over bites if desired.
10. Assemble the bites just before serving to keep the nori crisp.

Expert Tips for Best Texture

• Keep your veggie dice on the small side—this improves texture and helps everything blend perfectly.
• You can prepare the tuna salad up to 2 days in advance and store it in the fridge in a sealed container.
• Need more fiber? Toss in some shelled edamame or finely shredded kale for an extra nutritional boost.
• For an easy lunch on the go, pack tuna salad and nori separately and combine right before eating to keep that crispy seaweed intact.
• Swap up the presentation by sandwiching the tuna mix between two nori squares for fun “seaweed sandwich” bites, or try these moist canned tuna meatballs for another bite-size option.

I love eating these spicy tuna bites solo as a snack, but they also pair beautifully with a simple bowl of miso soup or an easy veggie fried rice to make a complete meal. They shine as crowd-pleasing party appetizers too — just set up a fun DIY nori wrap bar so everyone can customize their own flavor combos!

• Can I make it ahead? Yes! The tuna salad keeps nicely in the fridge for up to 2 days. Just wait to add the nori until serving to keep it crispy.

• How spicy is this? It’s mild to medium spicy by default. You can use less Sriracha to tone it down or more if you love heat.

Flavor Swaps and Add-Ins

• For a lighter, protein-packed dressing, swap out light mayo for Greek yogurt or do half and half.
• Use gochujang instead of Sriracha to enjoy its deeper, slightly sweet chili flavor.
• Add shelled edamame or finely shredded kale to amp up the fiber and volume without adding many calories.
• Try different proteins like canned salmon, rotisserie chicken, or mashed chickpeas if you want to switch things up.
• If you don’t have nori, serve this mix on rice cakes, corn thins, crackers, or inside lettuce or rice paper wraps.
• Make it heartier by stirring in diced avocado or cooked quinoa for extra texture and nutrients.
• For lower sodium, choose reduced-sodium soy sauce or Tamari and skip any added salt. Leave out sesame oil and seeds if you need a nut-free version.

Storage and Make-Ahead Tips

Store your tuna salad mixture in an airtight container in the fridge, good for up to 2 days. Keep your nori sheets or cut nori squares separate and only put them together just before serving to keep everything crispy and fresh. Avoid freezing the mayo-based tuna salad—it won’t hold up well and gets watery.

If you’re packing this for lunch or a snack, keep the tuna mix and nori in separate containers. For a fully make-ahead tuna option that packs and reheats well, try this 10-minute tuna quiche. To help keep your nori crisp, tuck a paper towel in with it to soak up any moisture. Don’t leave the tuna salad sitting at room temperature longer than 2 hours. If serving alongside warm rice, heat the rice separately and assemble your bites right away—pair it with this perfect fried rice recipe for busy weeknights.

Answers to Common Concerns

• Can I use fresh tuna instead of canned? Absolutely! Cook it however you like, flake it, then chill before mixing. Just note fresh tuna will have a firmer texture than canned.
• How spicy is this? It’s mild to medium spicy as written. Feel free to add less Sriracha if you want a gentler heat or more if you like things fiery—if that’s you, you might also enjoy our Spicy Cajun Garlic Butter Shrimp recipe.
• Is this gluten-free? It sure can be—just make sure to use Tamari or a certified gluten-free soy sauce.
• Can I make it vegan? Yes! Swap the tuna for mashed chickpeas or white beans and use vegan mayo. It’ll give you a similar creamy texture and flavor.
• How long does the tuna mixture last? Stored airtight in the fridge, it keeps great up to 48 hours.
• How do I keep the nori from getting soggy? Store your nori separately and only assemble when you’re ready to eat. For packed lunches, keep tuna and nori containers apart until serving.
• Can I cut down on the sodium? Definitely! Use low-sodium soy sauce or Tamari and skip additional salt or salty condiments.
