How to Make this Healthy Salad
Follow these simple steps to create the perfect low carb avocado tuna salad. It’s so easy, you’ll memorize it after one try.
Step 1: Prep Your Ingredients
Drain the tuna thoroughly. If using tuna packed in water, press out excess liquid. Finely chop the celery, red onion, and parsley. Cut the avocado in half, remove the pit, and scoop the flesh into a bowl.

Step 2: Mash or Dice the Avocado
For a creamier texture, mash the avocado with a fork. For more texture, dice it into small cubes. Both work well in this recipe.
Step 3: Combine Everything
In a medium bowl, add the drained tuna, avocado, mayonnaise, Dijon mustard, lemon juice, celery, red onion, and parsley.

Step 4: Mix Well
Stir everything together until well combined. Season with salt and pepper to taste. Taste and adjust — add more lemon juice for brightness or more mustard for tang.

Step 5: Serve Immediately or Chill
This salad is best served fresh, but you can refrigerate it for up to 24 hours. If storing, press plastic wrap directly onto the surface to prevent avocado from browning.
Step 6: Garnish and Serve
Garnish your low carb avocado tuna salad with a fresh lemon slice and a sprinkle of chopped parsley for a bright, refreshing finish. Serve immediately and enjoy — bon appétit!

Serving ideas
Serve in a bowl, spoon into lettuce leaves, or add to cucumber slices. The optional mayonnaise changes the flavor and nutrient content; check its ingredient list if you are avoiding a particular allergen. Tuna is fish, and mayonnaise may contain egg. Ingredient brands and portion sizes affect the finished meal.
