Tuna on Toast

This sophisticated take on tuna on toast draws inspiration from the classic Spanish pan con tomate, elevated with rich, oil-packed bonito tuna. The combination of sweet, slowly caramelised onions and fresh, zesty grated tomatoes provides a vibrant contrast to the savoury fish. Using high-quality tinned tuna and a good extra-virgin olive oil ensures a depth of flavour that turns a simple pantry staple into an elegant light meal.

As a high-protein option, this dish is perfect for a nutritious lunch or a Mediterranean-style appetiser when entertaining friends. The crisp baguette provides a satisfying crunch, while the fresh chives add a final touch of brightness. It is a wonderful example of how few ingredients, prepared with care, can create a balanced and healthy dish that feels truly indulgent.

Ingredients for Tuna on Toast

  • 1 tablespoon extra-virgin olive oil (preferably Spanish)

  • 1 medium yellow onion, thinly sliced

  • 1/2 teaspoons sea salt, divided

  • 4 plum tomatoes, halved lengthwise

  • 1 baguette, cut into 16 slices (1/2 inch each) and toasted

  • 1 can (170g) Spanish oil-packed bonito tuna (such as Ortiz), drained and flaked

  • 1 tablespoon chopped fresh chives

Heat oil in a medium pan over low heat. Cook onion until golden brown, about 30 minutes. (Add 1 to 2 tablespoons water if onions stick.) Add 1/4 teaspoons sea salt; set aside. Place a grater over a bowl. Rub cut surfaces of tomatoes across grater. Discard skins. Add remaining 1/4 teaspoons salt. Spread grated tomato over toasts (about 1 teaspoon per toast).
