Yum. this is making me hungry.
One thing I did last year and was glad I did - I prepared a bag of mixed vegetables, all chopped ready for soups (I make a lot of soups). I used carrots, leeks, beans, peas, and courgette (they don't help much but you have to use them somehow!) and then I could make a soup at short notice without hunting around for vegetables. So I've done it again.
I've also oven-dried sliced tomatoes (with a little olive oil, bay and salt) and frozen them in cartons.
