The most staple food in my country is rice. We usually have rice for breakfast, lunch and even dinner. Maybe a few will have bread for breakfast but the majority eat rice. This is because rice makes you feel full longer. A meal without rice feels like snacks only. Lol. Most of our viand also taste better with rice.
I really like the idea of rice as a staple. I could live with that. In the UK we use rice quite a lot, but also pasta and bread as a staple carb. I don't know where you are.
