I had such a surplus two years ago (last year was weird for some reason), I ran out of recipes and time, so many last tomatoes I just choped up and poured into ziplock bag to freeze. I used them as a sauce for pasta and they were just fine. Freezing broke them down.
I need to start planning my garden, thanks for a nice reminder :)

I had 10kg of cheap tomatoes to deal with a few weeks ago. I made a lot of the Country Style Tomato Sauce from Annabel Langbein's best of cookbook. It's great as pasta sauce, on pizzas or even in mexican chilli bean sauce. I also blanched some tomatoes, chopped them up and froze them to use instead of tinned chopped tomatoes in curries etc.
You could probably do semi-dried toms by slicing them and then putting them in a low oven until they dry out a bit...
Thanks for the link to the recipe.

Looks super yummy! We don't have a huge surplas but more than we can eat, so I plan to do something about it today! Enjoying them in winter will be the best!

Im glad you had success. I made another 7 jars today and I paid a dollar per kilo so what with the other ingrediants already in the larder it only cost me 5.oo upright. I just put mine in jam jars with lids that will pop each time they seal. (I always seem to have one that never seals tho)... Ive got a decent patch of ROmas out the front and I plan (Notice: plan...) to dry them and put them into small jars with olive oil. I also make tomato sauce but have a glut from last year and GHIU makes relish (just the edmonds book one but its YUM)
