Sprinkle the cut sides of the tomatoes with salt and allow to drain, upside down on a rack for 30 minutes. In a skillet, heat 1/4 cup oil over mod-high heat, and saute the tomatoes for 3-4 minutes on each side, or until they are softened but not brown. Transfer the tomatoes to a baking sheet and keep them warm, covered.
In a small skillet, heat 2 Tbsp oil over mod-high heat and saute the pine nuts, stirring, until they are golden. Transfer them to paper towels to drain. Add the butter to the skillet, and cook the garlic over moderate heat, stirring, until it is light golden. Add the parsley, and cook the mixture, stirring, for 1 minute. Season the mixture with salt and pepper, spoon it into the tomatoes, and top with the pine nuts.
