A sardine tostada?!!? You might think that I've gone a little mad but actually this isn't an original idea - I adapted it from an article on ideas of how to eat canned sardines. Sardines may not be a very trendy fish, but they also are an excellent source of omega-3 fatty acids, vitamin B12, selenium, and phosphorus.. Plus according to the FDS, According to the Food and , sardines contain far less mercury than most other fish.

As well as canned sardines having a long shelf life - and therefore very convenient for quick meals like this one - they're zero carb! Although I should mention that in this recipe I have used the Mediterranean style sardines from King Oscar, which have added herbs, bell pepper, olives, and garlic - which pushes the carb count up to 1g! Any variety should work for this recipe though.

Oh and if you're wondering if sardines are a traditional Mexican ingredient - did you know that Sardine Empanadas were a regional specialty in areas of Mexico that are deeply inland? Some areas don't have rivers or lakes and therefore the only fish they could enjoy was salted, dried, pickled, or canned.

How to Make a Low Carb Sardine Tostada

This recipe is *almost* no-cook - and if you wanted to skip the cooking and the tostada part, have a low carb sardine wrap instead! To toast the tortillas, simply place them on a baking sheet - I used Mission Carb Balance which are 4g net carbs each. Check out my full low carb tortilla comparison and review!

Broil for a couple of minutes on each side until crispy. Meanwhile, mash an avocado in a bowl together with some lime juice, salt, and pepper.

Spread the avocado over the toasted tortillas. Drain the sardines and place the fish onto the avocado.

Garnish with cilantro leaves and lime wedges, and serve immediately. 

This recipe makes a wonderful light lunch or quick late night snack!
