I like a good curry, and as a change for work lunches recently, I made Michelle Bridges' Vegetable and Tofu Curry. I got the recipe from her book, Total Body Transformation, but you can find it online here.
The flavours are bold and there is enough body from all of the vegetables in the curry to make it quite hearty. It is also low in calories, so it is a pretty healthy lunch.
It doesn't look that attractive, but if you like curry, this could be a way for you to enjoy it regularly without dialling up the fat and calories.
