Green Tomato Relish - for Hamburgers and Hotdogs

Wondering what to do with all the green tomatoes this fall?  We kept our tomatoes ripening slowly until the last frost and decided to salvage the green ones to make relish.  This relish turned out very well and tastes quite a bit like bread and butter pickles.  The colour is not dark green like store bought relish but the taste is really nice and if you really prefer a dark green you could add
a tiny bit of green food colour.  I use to do that until the family said they preferred I left it in it's natural colour!
