What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Thoroughly drain the canned mackerel to prevent the salad from becoming watery and bland.
- 2Use thick, plain yogurt (like Greek) so the binding is creamy but not runny.
- 3Let the finished salad rest for 5 minutes so the raw onion mellows and the dill flavor infuses.
- 4Lightly toast the bread before assembling to add crunch and guard against sogginess.
- 5For best texture, fold the dressing and mix-ins gently to keep the mackerel in pleasant flakes.
- 6Make the filling up to one day ahead; store it airtight in the fridge and stir before using.
- 7Pat the lettuce leaves completely dry so they don't introduce extra moisture to the sandwich.

High-Protein

Extra CrunchyExtra-Crunchy
Add 1/4 cup of finely diced apple or a tablespoon of toasted sunflower seeds for a sweet-crunchy contrast that complements the rich mackerel.

Herb SwapHerb Swap
Replace the dill with equal parts fresh parsley and chives for a milder, more versatile herb profile that pairs nicely with the celery and onion.
