My obsession with sushi grade ahi tuna runs deep. Whether it’s served poke style, sashimi style, or is lightly seared, I am all in. These sesame encrusted ahi tuna tostadas with spicy mango salsa are no exception. Perfect for lunch or a light dinner, this recipe is perfect nay day of the week.

Another reason I love it so much, is that ahi tuna is packed with protein and is really easy to prepare. It tastes great and leaves you feeling satisfied without feeling overly stuffed.

The ahi tuna in this dish is so fresh and bright you’ll feel like you are poolside at your favorite getaway. For this sesame crusted ahi tuna recipe, I paired the ahi tuna with spicy mango salsa (which can literally go on anything) for the perfect flavor and texture combination.

To add that extra crunch factor, I loaded the tuna on top of lightly fried and salted wonton tostadas. To finish the dish, I sprinkled a healthy amount of crushed cashews over everything. (because why not) Oh and don’t forget to dip all of these tasty bits into a dollop of my spicy creamy sauce. Perfection!

To make this dish a bit lighter, skip the spicy creamy sauce and use a touch of sriracha or soy sauce instead. Also, you can substitute the fried tostada for a lettuce cup! NO matter how you make it, these sesame encrusted ahi tuna tostadas with spicy mango salsa are incredible.
