Ingredients
Method
- Toast the bread until crisp on both sides, about 3 minutes depending on the toaster.
- Whisk the yogurt, lemon juice and mustard in a bowl. Fold in the apple and celery.
- Break the sardines into large flakes. Fold them into the dressing with a spoon, leaving some pieces intact.
- Divide the topping between the four slices and serve immediately.
Notes
For packed lunches, carry the topping chilled in a separate container and assemble just before eating.
