Ingredients

Main Ingredients

  • 12 oz sushi-grade ahi tuna, diced
  • 6 corn tostada shells
  • 1 avocado, diced
  • 2 green onions, thinly sliced
  • 1 tbsp sesame seeds
  • 1 tbsp cilantro, chopped

Dressing

  • 2 tbsp soy sauce
  • 1 tbsp sesame oil
  • 1 tbsp lime juice
  • 1 tsp rice vinegar
  • 1 tsp honey
  • 1 tsp grated fresh ginger
  • 1/2 tsp chili flakes, optional


Instructions

  1. Prepare the Dressing: In a small bowl, whisk together the soy sauce, sesame oil, lime juice, rice vinegar, honey, grated fresh ginger, and chili flakes if using. This dressing balances savory, tangy, and slightly sweet flavors to complement the tuna.
  2. Dice the Tuna: Cut the sushi-grade ahi tuna into small, even cubes to ensure each bite has a good texture and allows the marinade to coat well.
  3. Marinate the Tuna: Place the diced tuna in a bowl and gently toss with half of the prepared dressing. Let it marinate for 5 to 10 minutes to absorb the flavors without softening the fish.
  4. Prepare the Tostadas: Spread the diced avocado evenly over each corn tostada shell. The creamy avocado layer adds richness and balances the acidity of the dressing.
  5. Assemble the Tostadas: Spoon the seasoned tuna mixture over the avocado layer on each tostada.
  6. Garnish and Serve: Drizzle the remaining dressing over the assembled tostadas, then garnish with thinly sliced green onions, sesame seeds, and chopped cilantro for freshness and crunch. Serve immediately to keep the tostada shells crisp.

Notes

  • Always use sushi-grade ahi tuna from a trusted source to ensure safety and quality.
  • Assemble the tostadas just before serving to maintain the crispiness of the shells.
  • Add thinly sliced jalapeƱo for an extra kick of heat if desired.
  • Mango or cucumber can be added to the topping for a fresh, tropical twist and added texture.
