If cook for 2 person it is healthy but very wasteful in terms of
costing. Imagine the oil, gas, electricity, water, effort, oily
floor etc etc juz to cook dishes soup for 2 person eat liao chor
leh...
But looking at healthy aspects, it is wiser to cook at home. For me
we eat once a while cook at home dishes and sometimes go outside
eat. Strike of balance is needed
