Hi all,
I think that freezing courgette isn't going to work, peas or green beans are good from frozen.
I've found that "Sweet Potato", (The orange fleshed ones) are easy to grow in a pot in the summer (very pretty flowers, but need a lot of warmth and water) and you can store the resulting Sweet Potatoes for months dry (and they don't need to be in the dark). The last of last years is just shrivelling up now (I just slice a slice off the tuber, and leave it on the veg. rack (not in a bag), if you don't cut a slice for a while the cut end won't go rotten but form a thin, dry scar that you can cut off to get at the next slice etc.), so I've had it for 8 months. I also got my originals from Aldi, and next time they are on offer I'm going to get some more.
cheers Darrel
