Heat a small saucepan over medium heat. Pour in the oil and saute the green onions and garlic until soft. Do not burn the garlic! Add white wine. Reduce the liquid by half. Add the tomatoes and simmer until the tomatoes are warmed through. Do not allow the tomatoes to liquify. They must retain their integrity for texture. Season with salt and pepper. Add the parsley. Enrich the sauce with 2 Tbl butter and remove from heat. This sauce is not meant to be thick. Pairs well with standing rib roast or rotisserie chicken.
