Olasagasti Tuna Fillets in Sun-Dried Tomato Sauce

Tuna a la Siciliana is Basque fish prepared in the Italian tradition—a whole tuna fillet packed with a bright, bold sauce of sun-dried tomatoes, black olives, and oregano. With many tinned fish brands, the added ingredients can feel like an afterthought, but not here. This is a genuinely high-end meal in a tin.
