Hi Artemis!
Here's what I take to work on Green Days:-
1. Batchelors Pasta Sauces made up are great to take and very filling! Some of them
are Syn free and others are minimal Syns.
2. Heinz 98% Fat free Noodles are all free and good to take made up too - whack in
some stir fried veg night before if you keen

3. I find taking wholemeal rolls and boiled eggs & Quorn Sausages a good meal too.
4. Jacket Potatoes are great too - I usually get a plain one then buy a tub of
flavoured low fat cottage cheese from like Tesco or somewhere and eat the lot. Or
with beans as Heavensbug said.
Good luck!
