What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Drain the tuna very thoroughly and press it gently with a fork to remove excess liquid — this keeps the salad from turning watery.
- 2Use full-fat Greek yogurt for a creamier texture and richer flavor; nonfat yogurt can make the salad taste thin.
- 3Pat the romaine leaves bone-dry after washing so the creamy tuna mixture adheres properly without diluting.
- 4For the crunchiest texture, assemble the boats just before serving — the lettuce will wilt if left filled too long.
- 5Refrigerate any leftover tuna salad in an airtight container for up to 2 days; spoon it into fresh lettuce cups when ready to eat.

Spicy southwest
Add 1/4 cup diced roasted red peppers, 1/4 cup corn kernels, a pinch of cumin, and a minced jalapeño for a smoky, slightly spicy twist.
low fatLow-fat
Replace half the Greek yogurt with mashed avocado for a creamy texture with fewer calories and added healthy fats.
jainJain
Omit the red onion and fresh dill, and substitute a pinch of asafoetida (hing) for onion flavor; use a Jain-friendly yogurt alternative made from plant milk.
dairy freeDairy-free
Swap the Greek yogurt for an equal amount of dairy-free yogurt (plain unsweetened coconut or soy) to keep it creamy while avoiding lactose.

Frequently asked questions
Yes, you can substitute an equal amount of mayonnaise (approx. 1/2 cup) for a richer, more traditional tuna salad, but it will reduce the protein content and change the tangy flavor.
