These Mexican tuna tostadas are easier than you think: the perfect healthy meal with a lot of flavor. This recipe is relatively simple and quick to prepare, making it a convenient option for a tasty meal, whether cooking for yourself or hosting guests.

Tuna Ceviche Tostadas

The beauty of this recipe is how quick, economical, and tasty it is to make. I like to make it on a hot day when I don’t feel like spending time near the stove and instead enjoy valuable moments with my family. Ceviche (also spelled cebiche) is a popular way of combining fresh raw fish or seafood marinade in citrus juices like lime or lemon. The acid in the citrus juices helps to "cook" the fish by denaturing the proteins. However, I am using tuna in a can for this recipe because I know not everybody has a fish market close to where they live. 

There are many ceviche recipes that you will find in Mexico, some of which use fish (traditional ceviche and green ceviche ), shrimp, or a combination of seafood (Ceviche Mixto),  sometimes fruit, like jicama. So if you like seafood, look no further than these canned tuna ceviche tostadas! Not only are they quick and easy to prepare, but they're also healthy and bursting with flavor. With a zesty combination of fresh tomatoes, onions, cilantro, and avocado mixed with canned tuna and lime juice, these tostadas are sure to satisfy your taste buds. Don't miss out on this light and delicious meal - give this recipe a try today!

Instructions:

• Gently mix tomato, onion, Serrano pepper, and cilantro in a large bowl. Make sure not to over-mix it; it will become a salsa. This mix is more like a salad where you enjoy every bite of the ingredients in your mouth. (Please check the ingredients list below)

• Then, drain any excess liquid from the tuna. Carefully, with the help of two forks, stir the tuna into the rest of the ingredients in the bowl.

• Add the juice of half a lime and season with salt and pepper.

• In another bowl, mash the avocado to form a puree, and add a few drops of lime while mashing it to prevent the avocado from becoming brown. 
• Then, season with salt and pepper.

• To form the tostadas, spread a portion of the creamy avocado puree over each tostada and top it with the tuna mixture. 
• You can add a few slices of Serrano pepper and cilantro to garnish. Enjoy!

What is a Tuna Tostada?

A Tuna Tostada is a Mexican dish that typically consists of a crispy tortilla (tostada) topped with tuna and a variety of flavorful and colorful toppings. Nowadays, you can find a variety of recipes and even a fusion of Mexican and Asian flavors, often featuring ingredients like fresh sushi-grade tuna, avocado, lime juice, soy sauce, and various vegetables, like the one you find at the renowned restaurant Contramar in Mexico City.  

Can I make my own tostadas?

Yes, here are a few ways that you can make them at home:

• For a healthier alternative, you can bake them in your oven to dry the tortillas, place them on a baking sheet, brush them with vegetable oil or spam spray oil, and cover them with your cooling rack to keep them flat.

• Then, bake at 200 degrees (low temperature) for about 10 minutes.
• Alternatively, you can deep-fry the tortillas in vegetable oil in a large skillet over medium-high heat until golden, rigid, and crispy.

• Drain on paper towels. (This is the most common method used in Mexico).

How do you store your tuna tostadas?

Tuna tostadas are best enjoyed fresh to maintain their crispiness and vibrant flavors. However, if you have leftovers or need to prepare them in advance,  is better to place the tuna mix in an airtight container and in your refrigerator for up to 2 days.
