but anyway would you bring this up to your family to eat cereal at dinner?
As long as my financial condition is good, I won't be doing that because for me my family's nutrition and health is very important and that's why only allowing them to eat cereal for dinner would not be a good choice.
We often have different menu options at dinner time, at least twice to thrice we have some kind of meat at the menu even at dinner time. Most often it's either chicken which most people prefer or mutton which I personally prefer. And, only few days we may have lentils and vegetables at dinner time.
I won't say that we don't have rice at dinner time because once in a week, or sometimes twice we go for rice only dinner. But, there are many added things in that rice, like Potatoes, chicken, sometimes mutton. However, only in rare occasions we have simple rice dish in dinner.
