What kind of lunch to bring in autumn can be decided according to your own preferences. If you like meat, you can bring more meat, such as bacon beef. If you like vegetables, you'd better bring some carrots, bean sprouts and broccoli. These vegetables are rich in vitamins, so it is better to eat more vegetables in autumn.
If you can cook sushi, you'd better make some sushi, because sushi can replenish enough energy for your body. Sushi is simple, and there is no soup, so it is very convenient to carry. Just make it before you leave. Don't forget to bring drinks when you travel. You can bring some mineral water and fruit juice, and it is best not to bring carbonated drinks, such as coke and soda.
Sandwiches and salads are also very suitable for autumn travel. These two foods are healthier and easier to carry. When making sandwiches, put them in a fresh-keeping bag or use a fresh-keeping bowl. Salad can be put in a fresh-keeping bowl. I'm tired and thirsty when I travel in autumn. Eating a little fruit salad can replenish my strength.
