What should you pack to eat on a long day outdoors?

Few things are as disappointing as unwrapping lunch at a viewpoint and finding a damp, flattened sandwich and a bruised banana. A long day outside, on foot, on a bike, on a boat, deserves food that arrives the way it left. This is not about fuel numbers. It is about packing things that survive and still taste like something you wanted.

Sandwiches that hold

The enemy is moisture meeting bread. So:

• Choose sturdy bread. Focaccia, ciabatta, a good roll or a dense sourdough cope with hours in a bag. Soft sliced bread surrenders.
• Build a barrier. A thin layer of butter, oil-rich spread, or thick cheese against the bread keeps juicier fillings from soaking in.
• Keep wet things apart. Pack sliced tomato, cucumber or dressed leaves in a separate small box and add them when you stop.
• Pick fillings that like waiting. Hard cheeses, roast vegetables, frittata slices, hummus with roasted peppers, a smear of pesto: all improve after a few hours.

Wrap sandwiches tightly in paper and then foil or a beeswax wrap. Paper absorbs a bit of moisture; the outer layer keeps everything together.

Things that don't wilt

Delicate salad leaves are lovely at home and miserable after four hours in a rucksack. Better options:

• Grain or pasta salads with sturdy vegetables, dressed in oil and lemon rather than anything creamy.
• Whole firm fruit: apples, pears, clementines, a bunch of grapes in a box.
• Cherry tomatoes, carrots, radishes, snap peas, chunks of fennel: crunchy and happy at air temperature.
• A wedge of frittata, which is good at room temperature by design.

Salt and crunch

After a few hours moving, salty and crunchy is what we find ourselves wanting, and it is what makes a stop feel like a treat. Pack some:

• Salted nuts, crisps, breadsticks, taralli, crackers.
• Olives in a sealed tub.
• A piece of hard cheese like parmesan or aged pecorino, which travels well.

And something sweet: dark chocolate, dried fruit, a slice of cake or a few biscuits for the slow part of the afternoon.

Packing like you mean it

• Hard containers for anything soft. A light lunch box protects fruit and sandwiches from being sat on, which they will be.
• Heavy at the bottom, snacks at the top. Put what you will eat while moving in a hip pocket or the top of the bag, so you don't have to unpack everything at every stop.
• Plan several small stops. A mid-morning snack, a proper lunch, an afternoon bite. Easier to carry, and it breaks the day into pleasant chapters.
• Keep the cold things cold on warm days. An insulated bag with a cold pack helps anything with cheese, eggs or dressings. On hot days, follow your local food-safety advice for perishable food, or choose things that are happy unrefrigerated.
• Bring a small knife, a napkin and a bag for rubbish. Leave the place as you found it.

The little luxuries

A small flask of coffee or tea. A lemon to squeeze over something. A twist of flaky salt for the tomatoes. A tiny bottle of good olive oil for the bread. These weigh almost nothing and turn a pack lunch into a proper picnic at the top of something.
