This month it will mainly be a portion of home made syn-free soup (cheap and cheerful), a yogurt, 2 apples, a banana, an orange and a sharon fruit. Oh , and my redbush teabags for the day because it'll work out cheaper than joining the coffee / tea circle at work.
When I've got more money at my disposal it might include more interesting fruit, some meat with salads, etc.
Another fave of mine is a tin of mackerel in tomato sauce and some ryvitas. I mash up the mackerel and spread it on the ryvita and it's delicious, but I always feel like people are rolling their eyes because it's making the staffroom smelly so I'll leave this to the summer when I can eat on our table in the court-yard outside.
I like taking cous cous with finely diced red onion, pepper, courgette etc and some left over lamb, chicken or pork. I put a crumbled stock cube in, but don't add the boiling water until I'm ready to eat it - hot lunch with no need for microwave etc. Or the same, but with chickpeas and chorizo instead. Or with dried fruit. The possibilities are endless!
