Dried beef/diced beef
Many people like to eat beef jerky, which is more chewy and interesting than stuttering beef. And don't look at a small piece of beef jerky, which contains infinite energy and is made of compressed beef. It seems to swell slowly during chewing. Eat 1-2 and you won't be hungry. Moreover, the size of beef jerky is very small, which doesn't take up much space in our backpacks. It is very convenient and light to carry when taking the train.
Boiled corn
When we take the train, we can also prepare our own 1-2 boiled corn. Corn is a very healthy coarse grain with rich nutrition and low calories. Also very full, very resistant to hunger. The important thing is that many people like it. We can cook or steam corn in advance, then cut it into small pieces and put it into clean plastic bags. It takes no space to carry and is convenient to eat.
