Assemble at noon, not at 7am

The surest way to keep a sandwich from getting soggy by lunch is to pack the wet stuff — tomato, lettuce, pickles, sauce — in a separate container and put the sandwich together when you’re ready to eat.

If that feels like too much fuss, your backup is a moisture barrier. Spread butter, mayo, or cream cheese across both inside faces of the bread. It works like a raincoat. Then layer cheese or meat between the bread and anything wet so the tomato never touches the loaf.

Bread choice matters, too. Soft white bread is a sponge; sourdough or a crusty roll holds up way longer. Toasting helps even more. And keep hot things out of the picture — heat creates condensation, and condensation will wreck a sandwich faster than any slice of tomato will.

Takes 60 extra seconds and your noon self will thank you.
