Ingredients
 
 

  • 1 mini seedless cucumber sliced very thinly
  • 2 pinches salt
  • 2 medium russet potatoes 1½ lb with skin on
  • 1 tablespoon tamari soy sauce
  • 3 tablespoons avocado mayonnaise or regular mayonnaise
  • 3 tablespoons unsweetened dairy free yogurt I use almond milk yogurt
  • 3 tablespoons bonito flakes
  • 1 can canned tuna 5oz size can, drained
  • 2 teaspoons sesame oil or more
  • Salt and pepper to taste

Instructions
 

  • Place the sliced cucumber in a bowl and sprinkle salt. Let sit for about 3 minutes, then squeeze water out of the cucumber. Set aside.
  • Peel the potatoes and cut into one inch cubes. Place them in a large saucepan and cover with water. Cook the potato cubes for 10-12 minutes or until soft but not mushy. Drain well using a strainer.
  • In a large bowl, place the cooked potato, mayonnaise, yogurt, tamari soy sauce, and bonito flakes. Toss well, mashing the potato slightly with a fork.

Notes

Tuna potato salad can be refrigerated for up to 3-4 days, tightly covered. Freezing is not recommended as the texture of the potato changes significantly.
