Tezryu, if you don’t have Michael’s book I would recommend looking at the thread ‘what did you eat today’ as there are so many helpful post of people’s daily menus on there.
Good ideas for meals to take to work:
Dips such as hummus with plenty of celery, pepper and cucumber crudites ( I like raw broccoli too)
Full fat yoghurt pots with fruit – either berries or an apple or pear
half a frittata
salads with either chicken, tuna, salmon, eggs, cheese or any thing else you can think of
Soups in a flask – or if you have access to a microwave any stew or curry.
A chunk of cheese (calorie counted) or tub of cottage cheese with some salad or an apple.
Hope that helps, real food will taste better than the shakes – and be cheaper! 🙂
Finally look on the recipes tab as you may find ideas there
