An easy and low calorie side dish that could be served with any meat dish. I found this in Everyday Food magazine and have use Vidalia onions and added garlic for our taste. The Vidalia's are soooo sweet!

This recipe is so simple I was thinking, "Now why didn't I think of this"? Absolutely tasty, easy, devine, make-againable!! And again and again. I halved the recipe as there was just DH and myself having dinner. The tomatoes and garlic were fresh from the growers market that morning, so we had freshness on our side. I had considered skinning the tomatoes but decided just to follow the recipe as written. Next time I may remove the skins as DH is not keen on them. The flavours were superb. I served it slightly cooled but not quite at the room temperature stage. I served it with Sauteed Zucchini With Oregano and Feta, grilled Haloumi and mashed potatoes. DH was impressed and commented that we'll have to have this again. High praise indeed. A definite keeper. Made for Aussie / Kiwi Swap December 2013.

I made this, and I believe I enjoyed it, but I cannot remember. So, the recipe goes back yet again in my "try it" file, and this time, I intend to rate it.
