i'm about to start a 9 to 6 job soon and am on a tight budget so i don't have money to spend on meal replacement drinks. i'm wondering how to plan my meals though, because i'm not sure yet whether eating even though it's not lunch hour is acceptable, and if it is, how to pack a gigantic amount of food to work.

imagine a gigantic plastic container with 4 slices of bread, PB, lettuce, tomatoes and boiled chicken breast hehe. plus soya milk. everyday.
