Ingredients
Method
- Drain the tuna well and press out excess liquid.
- Mix mayonnaise, Dijon mustard, lemon juice, salt, and black pepper until smooth.
- Flake the tuna gently in a bowl.
- Add celery, onion, and parsley, then fold in the dressing.
- Toast bread lightly if desired.
- Add lettuce if using, spoon on the tuna salad, and close the sandwiches.
- Serve immediately, or chill the tuna salad before assembling.
Notes
- Pressing the tuna well is the main step that prevents sogginess.
- Store the tuna salad separately if making ahead.
- Add the extra teaspoon of mayo only if the mixture feels too dry.
