Spicy Marinated Vegetables and Sardines on Toast

This vibrant dish of spicy marinated vegetables and sardines on toast offers a sophisticated twist on a classic pantry staple. By quick-pickling shaved carrots, shallots, and radishes in sherry vinegar and toasted spices, you create a bright, crunchy contrast to the rich, savoury tinned fish. The infusion of toasted coriander and fennel seeds provides an aromatic depth that elevates the entire meal, making it feel far more indulgent than a standard sandwich.

As a high-protein lunch or light supper, this recipe is both nourishing and remarkably easy to assemble. The combination of heart-healthy sardines and crisp, raw vegetables makes it an excellent choice for those seeking a nutritious, energy-boosting meal. Serve the warm, garlic-rubbed baguette topped with plenty of zest for a fresh and satisfying finish that brings a Mediterranean flair to your kitchen.

Ingredients for Spicy Marinated Vegetables and Sardines on Toast

  • 1 1/2 teaspoons coriander seeds

  • 1/2 teaspoons fennel seeds

  • 8 small any colour carrots (about 170g total), scrubbed

  • 2 small shallots, peeled

  • 1 small serrano chilli

  • 80ml sherry vinegar

  • 6 radishes, trimmed

  • 2 tablespoons olive oil, plus more for drizzling

  • 1/2 baguette, split in half lengthwise

  • 1 garlic clove, peeled

  • 180ml mayonnaise

  • 3 (110g) cans sardines in water, drained

  • 1 lemon

  • A spice mill or mortar and pestle

Preheat oven to 218°C. Toast coriander and fennel seeds in a dry small skillet over medium heat, tossing often, until fragrant, about 2 minutes; let cool. Coarsely grind in spice mill or with mortar and pestle; transfer to a medium bowl.

Using a mandoline, shave carrots, shallots, and chilli into thin rounds; transfer to bowl with spices. Add vinegar and season with salt. Using your hands, massage mixture 20–30 seconds (this is just to get the flavours to meld faster). Let sit 10 minutes.

Shave radishes on mandoline into bowl with carrot mixture and add 2 tablespoons oil. Toss to combine and let vegetables sit another 5–10 minutes.

Meanwhile, tear baguette halves into 4" pieces and place on a baking sheet. Drizzle with oil and bake until golden brown and edges are lightly charred, 5–8 minutes. Remove toast from oven and rub cut sides with garlic; season lightly with salt. Spread a layer of mayonnaise over each toast. Top with a few sardines, then drained vegetables. Finely grate a bit of lemon zest over each.
