Ingredients:
- 20 oz canned tuna in water (four 5-oz cans), well drained
- 1 medium onion, finely diced (about 1 1/3 cups)
- 1 medium Granny Smith apple, cored and diced
- 1 avocado, pitted, peeled, and diced
- 3/4 cup real mayonnaise (adjust to taste)
- 1/2 tsp fresh lemon juice (or to taste)
- 1/2 cup sliced almonds or chopped walnuts, toasted
- 1/8 tsp black pepper (or to taste)
Instructions:
- Toast the nuts – Heat a dry skillet over medium heat and toast the nuts until golden and fragrant. Remove from heat and let them cool slightly.
- Drain the tuna – Open the cans and press the lid down firmly over the tuna to remove as much water as possible. If the tuna is too wet, the salad will become watery.
- Mix the ingredients – In a large mixing bowl, combine the drained tuna, diced onion, apple, avocado, toasted nuts, and mayonnaise.
- Season to taste – Add black pepper and lemon juice to taste, adjusting mayo as needed.
- Serve and enjoy! – Enjoy immediately or chill in the refrigerator before serving for an even more refreshing taste.
Tips:
- For extra crunch, try adding diced celery or shredded carrots.
- If you prefer a lighter salad, swap some of the mayonnaise with Greek yogurt.
- Make sure to dice the apple right before mixing to prevent browning.
- Store leftovers in an airtight container in the fridge for up to 2 days.

Variations and Substitutions:
- Swap Granny Smith apples for Honeycrisp or Fuji apples for a different sweetness level.
- Replace mayonnaise with mashed avocado for a healthier, creamy alternative.
- Use pecans or sunflower seeds instead of almonds or walnuts.
- Add dried cranberries for a hint of sweetness.
- Try using canned salmon instead of tuna for a different twist.
FAQs:
Can I make this salad ahead of time?
Yes! However, since avocado can brown over time, it’s best to add it just before serving. Store the salad in an airtight container in the fridge.
What can I use instead of mayo?
Greek yogurt, mashed avocado, or a combination of both make great substitutes.
Is this recipe keto-friendly?
Yes! As long as you keep an eye on the apple quantity, this salad can fit into a low-carb or keto diet.
Serving Suggestions:
- Serve on a bed of fresh greens for a light, nutritious meal.
- Enjoy with whole-grain crackers or pita chips for extra crunch.
