That sounds familiar. My wonderful fil started cooking for his large family in the Philippines...
...when he was a pre-teen. He remembers the mandate was to always stretch the expensive ingredients (meats, poultry, sausages, etc.) in any dish he cooked for the family. No one was allowed to have a main dish without plenty of rice! (I found this out the hard way, many years ago.)
His stews (sinigang, adobo, etc.) all have plenty of liquid. That way you can easily add flavor to a big pile of rice when you eat the stew.
Even the Filipino version of congee, called lugow, is made thick with the addition of tons of rice. It is cooked into a thick porridge by the long, slow cooking of the rice. Again, rice is the budget-stretcher, even in thick stews!
