I work for T---o and the amount of people with big families that come through the checkout with ready meals is unbelievable not just one or two but enough for the family for a week, if I bought anything like that for my 12 year old daughter she would want 2 or 3 for one meal they are so small. She isnt overwight and has a very healthy diet as we eat a lot of vegetarian food including pasta, rice etc she likes her veg but not much fruit, drinks lots of water but doesnt like fizzy drinks. I use veggie mince or quorn chunks to make meals with instead of meat which is low in fat. Oven chips maybe once a week, takeaways hardly ever.
Not a lot of waste in our house only when OH cooks every weekend and dishes up far too much unless I tell him before he starts, he should have got the message by now.
