I buy the snack packs in asda - not sure what make they are - not a well known brand. But theryre 3 for £1. I calculated them online and theyre free on green. Only come in 2 flavours though: Chicken n mushroom or tomato and vegetable. Idea for work lunch though!
Really must try and make my own - i assume ordinary cous cous is free...so could just add herbs/spices/soy sauce/lea in perrines? - (spelling!?!)
