Oven dried tomatoes

I could go to bed if my oven were not filled with tomatoes!  My neighbor Demos mentioned today that he had dried some tomatoes.  Our house is full of tomatoes!  Those from the CSA bag of course and all of the tomatoes my sweet husband has purchased for a winter of tomato sauce.  Demos works for a food processing company & "one of the chef's at work" told him that he should dry his excess tomatoes in a 225 degree oven for about 5 hours, with just a little olive oil & salt.  I tasted them & they were great.  Thus, my tomatoes went into the oven about 6:00 and now I wait for them to dry, instead of sleeping like my children.
