Topped with a cross between a chunky guacamole and a tuna salad, these tostadas are a super satisfying, no-cook lunch or dinner for a steamy summer night when turning on the stove is a no-go. Instead of fresh tuna, this recipe employs the tinned variety, making these tostadas accessible for any budget. The simple serrano and lime dressing is tart and spicy with a hint of creaminess that balances the lean nature of canned tuna. Eat the salad like a dip with a bag of totopos at your desk, or pack it up with a bottle of wine and assemble your tostadas outside for a picnic in the park or day at the beach.

Preparation

  1. Step 1

    Make the dressing: In a medium bowl, mix together the garlic, serrano, lime juice, mayonnaise, ½ teaspoon salt and ½ teaspoon pepper until well combined; set aside.

  2. Step 2

    Make the salad: Roughly chop the cilantro, chop the avocado, dice the red onion and tomato, and place everything in the bowl with the dressing. Add the tuna and ¼ teaspoon salt and toss until combined. Taste and add more salt as desired. Serve immediately, or cover and refrigerate for up to two days.

  3. Step 3

    When you are ready to eat, divide the filling among the tostada shells (about a generous ½ cup tuna salad for each tostada) and top with hot sauce, if desired.

So good! Endlessly riffable for a great no heat dinner! I did a quick pickle in the lime juice to mellow the alliums (extra garlic and a shallot) and jalapeño, then added smoked sea salt, freshly ground pepper and Greek yogurt to finish the dressing. In addition to the tomato and cilantro, I added an extra avocado, diced cucumber, and grilled sweet corn to clear out the veggie drawer!

It’s 100degrees today here in Denver, and this is the perfect meal to combat the heat. I made it as a “bowl” using rice instead of the tostadas and added toasted sesame seeds for that magic crunch. Fast, easy, perfect heat-busting meal.

I find that salting your tomato in advance helps it to shed water content and concentrate flavor. So as a first step, I placed the diced tomato in a bowl, sprinkled with Diamond Crystal Kosher Salt, and stirred to distribute the salt. Fifteen minutes later, I poured off the liquid before adding the diced tomato to the other ingredients. This was delicious! I found it even better for lunch the next day after the salad had chilled in the refrigerator.

Added leftover corn cut off the cob - delicious

Another evening of this go-to, quick, hot summer evening meal. Come home from work, prep, put it in the fridge, go work in the garden, come back to a nice cold meal. Great with sliced cukes on the side. We love this!

We used sushi grade tuna and ate it on seaweed and it was great !
