When a midday meal needs to be crisp and straightforward, this combination of canned tuna, eggs, and fresh cucumber rounds does the job. Each component holds its own cleanly without needing heavy dressings or complicated prep. The appeal is in the contrasting textures: meaty, tender tuna seasoned simply with salt and pepper, eggs boiled for just nine minutes, and cool, juicy cucumber slices providing crunch in every bite.

Why this one works

  • Requires only ten minutes of active prep time.
  • A nine-minute boil gives the eggs firm whites and rich, tender yolks.
  • Thick cucumber rounds stay crisp and provide a clean crunch.
  • Straightforward ingredients come together without complex sauces.

Ingredients

What you’ll need

  • 1 can (150g) tuna in water, drained Press out excess water thoroughly so the flaked tuna holds its shape on the plate without softening nearby ingredients.
  • 2 large (100g) hard-boiled eggs, halved A nine-minute simmer followed by an immediate ice water bath keeps the yolk centers tender and easy to slice neatly.
  • 1 medium (200g) cucumber, sliced into thick rounds Cutting these into half-inch rounds maintains satisfying structural snap and prevents them from softening.
  • 1/2 teaspoon (3g) fine salt
  • 1/4 teaspoon (1g) ground black pepper

Helpful details

A few things worth knowing

  • Submerge eggs immediately into an ice bath right after boiling to stop cooking and loosen the shells.
  • Press tuna firmly against the strainer or can lid to release excess liquid before seasoning.
  • Slice cucumbers into uniform half-inch rounds to give them sufficient firmness to scoop or pair with the tuna.
Variations

Ways to make it your own

  • Sprinkle a small pinch of fresh minced dill or chives over the egg halves before serving.
  • Dust an extra turn of cracked black pepper directly across the cucumber rounds for added aroma.
