Well done for being so positive and planning already! Next week you'll soon loose that 1lb.
Hmm i usually take to work with me quorn sausage sw quiche (or any other flav) i make it the night before then its lovely and cold for pack up lunches the next day.
Do you have access to a microwave, cooker? Scrambled eggs on toast, beans on toast, pasta 'n' sauce packets, savoury rice. You could make up a pot of soup such as potato and leek, vegetable and take it to work in a flask or mugshots.
Sandwiches with various fillings..
Today i had quorn ham in a sandwich with a packet of french fries, muller yog and a banana - filled me up till dinner time.
