I love chicken breast in a pita with hummus and salad topped with some plain unsweetened low fat yoghurt and unsweetened chilli sauce.
Another good one is homemade soup with wholemeal toast (without butter or margarine). Or if you can't be bothered making your own soup get some watties condensed tomato soup with diced tomato's. Tomato soup is the lowest-cal soup and full of antioxidants.
I also love baked potato's, you can fill with:
* ham and low fat cheese and chopped chives
* light sour cream sprinkled with paprika or chilli
* homemade gravy (made with cornflour and lowfat stock)
For a really really quick option have wholemeal toast (without butter or margarine) topped with sliced tomatos or avocado or unsweetened jam.
There you go, that's 1/2 a week of lunches sorted
