Hi, chanced upon this thread and thought of leaving a line. I'm a full time working mum and have always prepared dinner for my kids for the past few yrs.
My only equipment is a thermal cooker ( or magic cooker) - the type which u can cook for a while with the inner pot and leave it to simmer in the outer pot ( good thing is, no need to leave the electricity on for the whole day when you are not at home). Mine is a 2.5 litre cooker, just right for 2 kids and sometimes for myself. There is also an additional tray which u can use for steaming.
On weekends, i'll prepare portions of meat/fish & chopped veg ( carrots/pumpkin/cabbage etc) and freeze them according to the amount i intend to use for each meal. Defrost the meat/fish by bringing the required portion to the chiller section the night before, should fully defrost by morning.
So in the morning, i just cook the porridge and dump the veg in together. Before i turn off the fire and put the inner pot in the outer pot, I would stir in the meat/fish ( optional: seasoning for the porridge).
The porridge would still be warm when I reach home. Or if it is not warm enough, i will just heat it up which won't take too long.
Hope this helps.
