If you're like most people, you've probably eaten a Subway sandwich at least once in your life. And if you're like most people, you've probably wondered if it's safe to eat a Subway sandwich the next day. The answer is: it depends.
If the sandwich was made with fresh ingredients and stored properly, then it should be safe to eat the next day. However, if the sandwich was made with pre-cooked meat or vegetables, then it's not recommended to eat it more than 24 hours after it was made.
The bottom line is that if you're not sure whether or not a Subway sandwich is safe to eat the next day, err on the side of caution and throw it away. It's better to be safe than sorry!
