Answer: Most types of sandwiches can be safely left out at room temperature for about two hours — or one hour if the temperature is above 90 degrees Fahrenheit. If sandwiches containing these ingredients have been left out of the fridge for longer than two hours (or one hour above 90° F), they should be discarded.
2 hoursTo stay safe, sandwiches, salads, and other meals with perishable ingredients shouldn't be left at room temperature for more than 2 hours—max. Leftovers should also go back in the refrigerator within 2 hours.
Stick with just the meats, cheese and lettuce/spinach and some mayo. If you wrap the whole thing (including the outer paper wrap) in 2 layers of plastic cling wrap, the sandwich should keep just fine for up to 3 days in the refrigerator.
To seal in all the flavor and keep the sandwich together, wrap the sandwich tightly in plastic wrap before refrigerating. The bread will soften slightly overnight, but the crusty exterior will keep everything contained when you're ready to unwrap and eat.
If it sits in the fridge, and well wrapped, it should probably last in decent quality for a day or even two. If it's in your lunch box, the sooner you eat it, the better.

Wrap & freeze – Cut sandwiches in half then wrap tightly in plastic wrap. Place in the freezer. Keep sandwiches in the freezer for up to 3 months. Thaw & pack – Place sandwiches in the fridge the night before to thaw.
6 hours maximum, if the sandwich contains meat and/or mayonnaise, unless the lunchbox has the capacity to keep food cold. If your lunch is a peanut butter sandwich, a cookie, and an apple, then it will last much longer.
