Begin by draining a can of high-quality tuna and placing it in a mixing bowl. Use a fork to break up the tuna gently, ensuring there are no large chunks. Add in creamy mayonnaise, diced celery for crunch, diced onion for flavor, and a squeeze of fresh lemon juice. Mix all ingredients together thoroughly until well combined.

Lay out a clean cutting board or surface to assemble your Tuna Salad Nori Wraps. Take a nori sheet and place it flat, shiny side down.

Spoon a portion of the prepared tuna salad onto the center of the nori sheet, leaving about an inch of space on the sides.

Start rolling the nori away from you, using your fingers to tuck the filling in as you go. Wet the edge of the sheet with a bit of water to seal the wrap.

Once rolled, turn the wrap seam-side down and slice into bite-sized pieces.

Store any remaining tuna salad or nori wraps in an airtight container in the fridge for up to three days.
