What can we eat when we immigrate to Mars?

If you can really immigrate to Mars one day, you can only eat the food carried on the earth according to the current technology. It is impossible to grow food on Mars with current technology, but anything is possible. Maybe in the future, technology can plant plants on Mars, or humans can work, study and live directly on Mars. This is just a bold push. After all, you can only do it if you want to.
