Is it convenient to bring anything to eat when traveling?

Traditional tourism can bring very limited food, usually fast food. If it's not delicious, it's all preservatives and various additives. If you need an outdoor picnic or camping, it is recommended to bring a "solar oven". Wherever you go, where you bake, and where there is sunshine, you can make delicious food. Light weight, small size and very convenient to carry. Bake whatever you want in the kitchen, and eat hot food when you go out, which is also nutritious and healthy.
