This sesame tuna sandwich will satisfy any Asian sandwich craving. The tuna is first cooked in sesame oil, broken into chunks, and then dressed with toasted sesame seeds and more sesame oil. Doubling up on the sesame gives the tuna a punch of flavor and nuttiness. My son, who is not a tuna steak fan, was totally won over by this one! He even made special requests for it.

Can you cook with sesame oil?

There are two kinds of sesame oil: regular untoasted and toasted. Untoasted is light in color and has a higher smoke point. Therefore, it can be used for cooking. Toasted sesame oil is dark and has an intense nutty flavor because the sesame seeds have been toasted. However, it has a low smoke point and is unsuitable for cooking. Toasted sesame oil is considered a finishing oil.

This recipe uses both regular and toasted sesame oil. The former is used to cook the tuna, and the latter is added at the end to amp up the sesame flavor.

The sauce:

There is the wasabi mayo which adds a little zip and extra interest. It imparts creaminess and heat that work so well with the sesame tuna. It is splendid! The amount of wasabi in the recipe provides just a little heat, so if you like it hot, please feel free to add more.

The toppings:

Lettuce, cilantro, sliced tomato, and cucumber finish off the sandwich. I love the crispness of the cucumber in here. It adds as much value to the sandwich as the tuna and wasabi mayo by providing a refreshing crunch. Do not leave it out. It is a must-have ingredient! Trust me.

By the way, if you are wondering why I’m using a wheat roll instead of a sesame roll or bun on this SESAME tuna sandwich, that’s a good question. Well, I have a good answer. This recipe started when I bought some beautiful wheat rolls from the store. They inspired me to create a sandwich recipe. As you can see, the recipe was sesame-themed, but I didn’t have the heart to drop the wheat rolls like a hot potato (or a hot roll, in this case). That’s why they made it into the photos, and the sesame rolls didn’t 🙂

Have a wonderful week!
