One of my favorite foods to eat here in the Philippines is cassava leaves or banana heart cooked in coconut milk. 
Either one served over rice make a nutritious healthy meal.
There is no reason someone has to buy meat or fish because meals like these are delicious. 
The Philippines has many poor people who only want meat with their rice. 
Sadly, few know of these dishes which can be made from items that many can get for free.
They only have to buy their rice.
We use the tender green leaves of the cassava or shred the banana heart
