I have previously shared some Japanese-style salads, including iceberg lettuce with ginger dressing and green salad with sesame dressing. This tuna avocado salad recipe is my most recent favorite. If you are looking for a healthy tuna salad without mayo, I highly recommend it.


To compose this salad, you will need:

plates containing ingredients for the salad
  • ripe avocado
  • good quality canned tuna, drained
  • mixed lettuce: I recommend using a mix of different types of lettuce for salads whenever possible for different flavors and textures.
  • other add-ins: carrot, cherry tomato, and cucumber. These add-ins will bring more colors, textures, and freshness to the salad.

Easy Soy Sauce Salad Dressing

This Japanese-style soy sauce dressing (also called shoyu salad dressing) goes so well with all ingredients in this avocado tuna salad. It is quick and easy to make, light, savory, and umami.

The essential components of the dressing are soy sauce, rice vinegar, and toasted sesame oil. You can also add minced garlic, salt, and pepper to flavor it to taste.

Related: this dressing can also be used on my cucumber and tofu salad.

Recipe Notes

Here’s how I like to plate the salad:

1️⃣ First, toss the mixed lettuce, julienned carrot, cucumber and cherry tomato with half of the dressing first. Then arrange them on a serving plate. 

2️⃣ Lastly, top with avocado slices and tuna flakes. Drizzle the remaining dressing over everything.

  • If you don’t have avocado on hand or it is not in season, you can try using boiled eggs instead.
  • If you don’t have toasted sesame oil, replace it with your choice of vegetable oil for salad dressing. However, the sesame oil will add a nutty aroma, making the salad more delicious.
  • Other ingredients you may add to the salad are sliced radish and corn kernels.
