£100 food challenge: Setting the scene....

So, I feel I should make a few things clear in preparation for this challenge, namely that:

1. the kids have school lunches so I will not have to include their lunches during the week in this menu.  However it will include both mine and Nick's weekday lunches, and all weekend ones. 
2. during the challenge, there will be a half term holiday.  During this week, I will have to factor in lunches and snacks for the kids during the day.
3. We are away 5th-6th of February visiting family and attending the chinese new year celebrations in Trafalgar square and London's west end.  I will, for obvious reasons, not be including the food eaten during this time in the challenge.
4. I have a pretty good store cupboard including, amongst other things; a variety of dried beans, bulgur wheat, wholegrain rice, LOTS of spices, dried lentils and odds and ends of pasta. In the freezer I have some frozen berries we picked last autumn, some frozen apple sauce we made, a few wild Alaskan salmon fillets, a couple of tubs of cannellini beans I cooked up in a batch, various assortments of vegetables and some home made chicken stock.   Whatever I haven't used up before the start of the challenge will definitely help me to achieve it!

With all this in mind, I am already collating ideas and recipes - I still think it's gonna be nigh on impossible, but I WILL give it a good go......
