Some mornings, the anticipation of lunch is all that gets you through work or school. The juicy vegetables and creamy spreads that make your sandwich such a lunch highlight can also turn it soggy, even if you make it fresh in the morning. No matter what ingredients you like in a sandwich, always start in the same way: with crunchy, crispy bread.
If you keep wet and dry ingredients separated until lunchtime, all your sandwich components will stay crunchy. Try packing lunch ingredients in two small containers: one for the bread and cheese and the other with cold cuts, vegetables and any other items that make your sandwich slippery. If your sandwich includes sauces or spreads that make bread soggy, such as jelly or mayonnaise, purchase them in individual packets or pack small amounts in separate containers and build your sandwich at your desk. Pack a butter knife for spreading.
If you're unable or unwilling to make your sandwich at lunchtime, construct it in the morning in a way that keeps wet and dry ingredients from touching. Layer slices of hard cheese on each slice of bread and stack veggies and meat between them. For a sandwich that doesn't include cheese, place dry slices of meat on the bread, or spread the bread with a thick spread such as hummus. You can also use lettuce as a barrier, but dry it first with paper towels.
