A bright, crunchy tuna salad that pairs creamy tuna with crisp apples, celery, and a lemon-Dijon dressing. Ready in about 10 minutes and perfect for sandwiches, salads, or meal prep.
Core and dice the apple into small pieces. Finely chop the celery and red onion. Toss apple with a teaspoon of lemon juice to prevent browning if desired.
In a medium bowl, whisk together mayonnaise, Dijon mustard, and lemon juice. Season with salt and pepper and taste.
Flake the drained tuna into the bowl. Add apple, celery, onion, and herbs. Fold gently to combine, keeping chunks intact. Fold in nuts last if using.
Serve immediately on bread, in lettuce cups, or over greens. Store in an airtight container in the fridge for up to 48 hours.
Notes
Swap half the mayo for Greek yogurt for a tangier, lighter version.
Add chopped pickles, capers, or a teaspoon of honey for variations in flavor.
