rice with sweet potatoes

Philippine President Arroyo announced and advised the Filipinos to mix rice with yams or sweet potatoes. I do think this is a good alternative or substitute during this time of crisis. When I was still in the P.I. I used to eat "ube" or "kamote" for lunch together with "ginamos". To me, it was a good meal. Even here in the U.S., rice is limited to each consumer. Wow, this makes me think of the "Revelation" in the bible. I hope so not... The price of gas is going up and there is a great scarcity of rice all over the world. God help us!
