Throw the trays in the oven and roast at 160c for a couple of hours. I tend to do this in the evening then turn it off before bed and leave the trays in there overnight. Because the oven is on for such a long time you want to make a few trays full to make it worth your while, or maybe throw in a banana loaf or two at the same time?! After roasting for a few hours the tomatoes will caramelise beautifully, with all the liquid cooked out of them they will look like this...

Use a spatula to scrape the veges into the food processor, making sure you include the lovely sweet sticky bits stuck to the sides and bottom. Blitz it up, add a drizzle of olive oil or thin with a little water if too thick for your liking.
And there you have your starting point for many a delicious meal...although I love it simply tossed through spaghetti with lots of parmesan.
