Peel the tomatoes. To do this put them in a bowl filled with boiling water (not a job for the kiddies!). After that if you want to make tomato paste, blend them in a blender and add a bit of salt. If you jusr want to make tomato pasta sauce, i usually just chop up the tomatoes into cubes and fry them along with onion and garlic, plus extra vege of your choice (mushrooms and eggplant usually are mine), plus tomato paste to thicken it a bit, seasoning and any herbs you like (corriander and parsely are good).
edit: i forgot to say that if youre making tomato paste youre going to have to strain in through something fine to get rid of the seeds.
