If you’re into quick, no-fuss meals that taste like they came from your favorite sushi spot, these spicy tuna salad bites are about to become your go-to. It’s basically a mash-up between a tuna salad and sushi hand rolls, minus the rolling stress.

We’re talking creamy Sriracha mayo tuna, crisp cucumber, celery, and bell pepper for crunch, all spooned onto nori seaweed squares for that salty umami snap. It’s light, yet super satisfying. Think of it as your protein-packed, fiber-rich lunch or snack that doesn’t need reheating or babysitting.

I love this recipe because it’s endlessly versatile — pile it onto rice or corn thins, crackers, or shove it in a wrap. And honestly, it’s just really fun to eat.

What You’ll Need

Here is what you’ll need for these spicy tuna salad seaweed bites. Find the full measurements in the recipe card below.

• Canned tuna – lean, high-protein, and affordable.
• Light mayo – keeps it creamy without the heaviness. Use Greek yogurt instead of or with mayo for extra protein.
• Sriracha chili sauce– brings the heat and some zing. Swap sriracha for gochujang if you want a richer, sweeter heat.
• Cucumber, red bell pepper, celery – add fiber, crunch, and freshness. Add shelled edamame or green peas to bulk it up with more fiber and protein.
• Green onion – gives a subtle sharpness and pop of flavor.
• Seasonings & Extras: Light soy sauce – umami booster (regular soy or Tamari are also great), rice wine vinegar or lemon juice for a little acidity to brighten the whole thing, sesame oil for nutty, toasty flavor, and toasted sesame seeds for garnish and crunch.
• Nori seaweed sheets – cut into squares, like mini wraps for your tuna salad. Serve on rice cakes or corn thins if you’re out of seaweed.

Recipe Tips

• Don’t go too chunky with the veggies—smaller dice = better texture.
• The tuna salad can be made up to 2 days ahead and stored in an airtight container in the fridge.
• Want more fiber? Throw in some edamame or finely chopped kale.
• For an on-the-go snack, pack the tuna mixture and nori separately and assemble just before eating to avoid sogginess.
• You can even sandwich the mix between two seaweed pieces for a little “seaweed sandwich” situation.

Serving Suggestions

I love these on their own as a snack, but they’re also fantastic with miso soup or a side of rice if you want to turn them into a meal. They’re great as party bites too—just set up a little DIY nori wrap bar and let everyone build their own.
