Radish Tuna Salad Recipe

Why Radish?

One day I tossed in a handful of those thinly sliced radishes I’d forgotten existed. The sharp bite, the slight crunch, suddenly my tuna salad felt like a punch of spring in my mouth, instead of just cold fish and mayo.

Everyone talks about quick lunches, but rarely do they make you pause. Radishes, with their peppery bite and faint celery aroma, turn an average tuna salad into something I actually look forward to. And no fancy ingredients, just what’s in the fridge.

Right now, it’s about grabbing something that fuels without fuss. Sometimes, it’s the simplest ingredients that shake up the humdrum.

I didn’t plan for radishes, just a little whim, and it changed everything. Guess I like the idea of sneaking flavor behind the scenes, making me wonder what’s hiding in my everyday food.

How This Recipe Began

I started making this salad when I had leftover radishes from another dish and didn’t want them to go to waste. Mixing them with tuna created a crisp, savory combination that’s now part of my weekly rotation.
