When I was first dating my husband, we went to a small restaurant in Moss Landing and I had this dish. The sweet tomatoes, sour lemon and salty olives and capers are wonderful with the halibut. The chef was kind enough to list the ingredients for me. What I didn't remember exact amounts for, I improvised and it's close enough for me to what I had that day! If you can't get good cherry tomatoes, use any tomato chopped small. I've also subbed half the olive oil for stock when I'm feeling dietetic and that's good too. Not AS good, maybe, but good!
