How to make Tuna Tostada Recipe

Are tostadas healthy?

Tostadas can be a healthy food option depending on the ingredients and preparation methods used.

• Tostada shells: Tostada shells are traditionally made from corn tortillas, which are a good source of fiber and lower in calories compared to flour tortillas. However, tostadas that are deep-fried can be high in calories and fat. Baked or air-fried tostadas are a healthier alternative.
• Toppings: Tostadas can be topped with a variety of healthy ingredients such as fresh vegetables, beans, avocado, and lean proteins like grilled chicken or fish. However, some toppings like sour cream, cheese, and high-fat meats can add excess calories and saturated fat.
• Portion size: The size of a tostada can greatly impact its overall healthiness. A smaller tostada with lean protein and healthy toppings can be a healthy meal, while a larger tostada with excess toppings and a deep-fried shell can be high in calories and unhealthy.

Substitutions

Here are some ingredient substitutions you can use to make tuna tostadas:

• Tuna: If you don't have or don't like tuna, you can substitute it with other types of fish such as salmon, halibut, or shrimp.
• Avocado: If you don't have avocado, you can use guacamole or mashed cooked peas instead.
• Orange juice: If you don't have orange juice, you can use lime juice or lemon juice instead.
• Mayonnaise: If you don't like mayonnaise, you can use plain Greek yogurt or sour cream instead.
