Soggy sandwiches are a moisture problem, not a time problem.

A sandwich sogs out because wet fillings soak into the bread — it’s not the hours in the lunchbox that do it.

The fix is to block the moisture or remove it. The classic trick: spread something fatty on both slices of bread before you add anything else. Mayonnaise, butter, cream cheese, hummus — the fat works as a waterproof layer. Works way better than people expect.

Then control the wet stuff. Pat lettuce bone-dry with a towel. Slice tomatoes thin and scoop out the seeds. This sounds fussy, but it’s the difference between a decent lunch and a sad one.

If you want to go full pro, pack the wet ingredients separately and assemble at your desk. Takes 20 seconds and your sandwich tastes like it was made fresh — because it was.
