If you’re using standard sliced sandwich bread, buy a square loaf from a baker or supermarket that bakes their own bread in order to get the freshest bread possible. [3] X Research source Certain types of bread also work best with particular fillings. If your sandwich will have heavy solid ingredients like meat and cheese, use a more robust crusty bread. If your sandwich will have a soft and more viscous filling like egg mayo, use a fluffier white bread that the ingredients will cling to. [4] X Research source
You might also consider packing wet ingredients like tomatoes separately in their own container, and adding them to the sandwich immediately before eating.
For best results, never put the condiment directly on the bread.
If you make your sandwich a day in advance, store it in the refrigerator overnight wrapped in foil or plastic wrap and placed in an airtight container. [11] X Research source
