The ULTIMATE Tuna Sandwich | Spanish Empanada-Style Tuna Sandwich

This Spanish Empanada-Style Tuna Sandwich, known as Sandwich de Atun al Estilo Empanadilla, is what I consider to be, the Ultimate tuna sandwich. It´s packed with an insane amount of flavors, made with the simplest ingredients and done in just 30 minutes.

Spanish Empanada-Style Tuna Sandwich
You can serve this tuna sandwich right out of the oven, or let it sit and serve at room temperature. Either way, serve it next to a cold Estrella Galicia, a typical Spanish beer from the region of Galicia, and you will have an instant trip to beautiful España.

Spanish Empanada-Style Tuna Sandwich
For the bread I used typical white sandwich bread. But you can also use whole wheat, multigrain of even gluten free. Just make sure to lightly toast the bread before adding the tuna mixture. This ensures the sandwich won´t get soggy.

TIPS & TRICKS to Make this Recipe: I baked the sandwiches to get that empanada effect. But you can always lightly fry them in some olive oil for 2 minutes per side.

    This looks delicious! Can’t wait to try this. I was in Spain in September visiting my family and I loved everything TUNA! Quality of the tuna is everything, of course, (so back in the U.S., I only use albacore to make tuna dishes).

    Quick question – do you sell Spain on a Fork “Aprons”? They would be a big seller, for sure, and I would buy several – for me and for gifts…..

    Thanks Albert – love your recipes! Anna
