The best picnic sandwiches are sturdy and full of flavour. Pickles help because they keep things interesting without turning bread soggy, as long as you use them smartly.
Spread condiments on the inside of the bread with a butter barrier. Choose fillings like cheddar and brown pickle, ham and golden piccalilli, or chicken and achar. Avoid watery salad unless it is packed separately.
Wrap sandwiches tightly, slice at the last minute and bring a jar for serving if you are feeling generous.
