Ingredients

Serves 4 as appetizer or 2 as light meal.

• 8 oz (225g) sushi-grade ahi tuna
• 4 tostada shells (crispy flat tortillas)
• 1 ripe avocado
• ¼ cup sriracha mayo
• 2 tablespoons soy sauce
• 1 teaspoon sesame oil
• 1 tablespoon lime juice (plus wedges for serving)
• 2 tablespoons sliced green onions
• 1 teaspoon sesame seeds (black or white)

Step 1: Prep the Tuna

Step 2: Make the Sauce

1. Place cubed tuna in a medium bowl. Pour half the sauce over it. Gently toss to coat.
2. Save the remaining sauce for drizzling.

Step 4: Mash or Slice Avocado

Step 5: Assemble

2. Top with the sauced tuna.

Storage Notes

Do Not Store Assembled

Tostadas get soggy almost immediately. This is a eat-right-now recipe.

Prep Ahead Instead:

• Tuna: Cube and mix with sauce up to 2 hours ahead. Keep refrigerated.
• Avocado: Mash just before serving (it browns fast).
• Tostada shells: Store in a sealed bag at room temperature for weeks.

Leftover Tuna Warning:

Raw tuna does not keep once mixed with sauce. Make only what you’ll eat immediately.
