Honey, can you get hold of a wide-mouthed flask? I know they do them at Lakeland. Then you can take pasta and sauce, stew, soup, other left-over stuff and it's easily contained, kept warm and you can eat it straight from the flask.

How about pate-type things on crackers/oat cakes/rice cakes? You can make good pates using dried beans. Soak cannellini beans/borlotti beans/chickpeas overnight and cook until tender. Then mash or blend them and mix with some combination of garlic/chili/herbs/tomato sauce/mayonnaise/yoghurt/olive oil, plus a little of the cooking water to make your prefered texture. If you make it fairly dry it could also go in a sandwich. Then you can take fresh salad things to go with.

Do you like sardines? They're not stinky in the way tuna is and you can mix with mayonnaise, a LITTLE finely chopped onion, a finely chopped tomato to make a very yummy thing to go on crackers.

Can't think of anything else useful at the moment!
