Grilled Toast

Preheat the oven to 225 °C on the grill setting and line a baking sheet with parchment paper.

Cut the Fontina into small cubes and slice the green olives.

Lightly toast the bread slices, then place them on the prepared baking sheet.

Spread the toasts evenly with passata (strained tomatoes).

Drain the tuna, break it up and distribute it over the toasts.

Sprinkle corn and the Fontina cubes over them, and finally arrange the olive slices on top.

Sprinkle with oregano.

Grill the toasts in the preheated oven until the cheese has melted and is lightly browned.

Remove from the oven hot and serve immediately.
