How to make flavorful tuna tostadas

Prepare Tuna:

• Ensure the tuna is sashimi-grade, meaning it's safe to eat raw. Slice the tuna into cube-sized pieces.

Prepare Marinade:

• In a large bowl, whisk together soy sauce, rice vinegar, agave, and sesame oil. Adjust the flavor to your liking. 

Marinate the Tuna:

• Place the cubed tuna in the bowl. Gently toss to coat the tuna evenly with the marinade. Let it marinate for about 10-15 minutes in the refrigerator.

Chop the vegetables:

• Using a chopper or a knife, chop the red bell pepper, cucumber, jalapeno, and mangoes. 
• Mix it in with the marinated tuna.

Assemble Tostadas:

• Place the marinated cubed tuna and vegetables on top of each tostada.

Garnish:

• For extra flavor, squeeze lime on top. 
• Sprinkle fresh cilantro on top of the tuna tostadas for more flavor. 

Serve Immediately:

• Tuna tostadas are best enjoyed immediately to maintain the crispiness of the tostadas and the freshness of the tuna. 

Substitutions

• Tostadas: Substitute tostadas with tortilla chips, pita bread, store-bought tostada shells, or even lettuce cups for a lighter option.
• Sashimi Grade Ahi Tuna: If sashimi-grade tuna is unavailable, use sushi-grade salmon, canned tuna(can of tuna), or cooked shrimp as a substitute but still achieving that delicious flavors.
• Soy Sauce: Replace soy sauce with tamari or coconut aminos for a gluten-free alternative to achieve weight loss.
• Rice vinegar: Substitute with apple cider vinegar. 
• Agave: Replace agave with honey, maple syrup, or simple syrup for sweetness.
• Sesame Oil: Substitute sesame oil with extra virgin olive oil or avocado oil for a different flavor profile.
• Cilantro (for garnish): Replace cilantro with parsley, green onions, red onion, green onion, serrano peppers, black pepper, black beans or microgreens for a fresh and herbaceous garnish.
• Lime juice (for garnish): a squeeze of lime gives it more flavor, substitute with lemon. 

Equipment

• Chopper
• Knife
• Cutting board
• Bowl
• Measuring spoons
