Prep smart: tricks that save time
Plan to prep the ingredients that keep well ahead of time — chop cucumbers, olives and dill up to a day in advance and store them separately so the salad stays crisp. Use a fork to roughly mash the avocado for a bit of texture rather than pureeing it completely.

Ingredients you’ll need
120 grams canned tuna (packaged in water) ((or about 4 ounces)), 1/2 a medium-sized avocado, 1/4 cup plain greek yogurt ((benefits of Greek yogurt)), 1/2 cup English cucumber, diced, 1/4 cup green olives, chopped, 1/4 cup fresh dill, chopped, 1/2 a lemon, juiced, 1 tsp garlic powder, Salt + pepper to taste

Ingredient swaps and quality pointers
- Tuna: Choose tuna in water for a lighter texture; oil-packed tuna will add richness but also more calories.
- Avocado: Use ripe but firm avocado so it mashes smoothly but still has some body.
- Greek yogurt: Opt for plain Greek yogurt—it’s higher in protein and thicker than regular yogurt.
- Olives: Change the olive variety (kalamata or Castelvetrano) to shift flavor intensity.
- Dill: Fresh dill is best; if using dried, start with a small pinch and add to taste.
Step-by-step method
- Dice cucumber, and chop olives and dill. Set them aside in a small bowl so they’re ready to fold in.
- Mash avocado in a large bowl until slightly chunky. Then, add all other ingredients to the bowl, including the drained tuna, Greek yogurt, lemon juice, garlic powder, and salt + pepper.
- Mix everything together until well-combined, adjusting seasons to taste and adding a splash of lemon or a pinch more salt if needed.
- Scoop tuna salad into lettuce wraps, or add it to sandwiches, toasts, pitas, or salads. Leftovers can be stored covered in the fridge for a few days.
Timing and visual cues to watch for
- Prep time: about 5–10 minutes.
- Look for: avocado mashed but not pureed, tuna flakes mostly intact, and the mixture holding together without excess liquid.
- Chill: if serving cold, a 10–15 minute rest in the fridge helps flavors meld.
Best ways to serve this salad
Pair this salad with something crunchy or grain-based for contrast or keep it light with leafy greens.
Serving ideas
- Spoon into romaine or butter lettuce leaves for low-carb wraps
- Layer on toasted whole-grain bread with sliced tomato for an open-faced sandwich
- Mix into baby spinach or arugula for a quick composed salad
- Stuff into a pita pocket with extra cucumber for a picnic-friendly option
Storing and keeping it safe
Store in an airtight container in the refrigerator for up to 2–3 days; avocados will darken slightly but the lemon helps slow browning.
Storage reminders
- Keep any extra olive or cucumber pieces separate if you want maximum crispness the next day
- Do not freeze — texture will degrade (especially the avocado and yogurt)
- If serving again, stir and taste before serving; add a squeeze of lemon if flavors have dulled
