Place raisins in a small bowl, cover with hot water, and set aside. Heat a saute pan with oil in the oven. Add onion and cook until softened and lightly browned. Add garlic, pine nuts, capers, oregano, red pepper flakes, and bay leaf; cook, stirring for about 2 minutes. Add wine and cook for 2–3 minutes, or until wine is almost evaporated. Add the tomatoes, raisins with soaking liquid, vinegar, sugar, and salt. Cook for 15 minutes. Sauce should be thickened slightly. Remove from oven, stir in parsley, and set aside; keep warm.
Pull hot coals forward in oven. Oil a Mugnaini Tuscan Grill and set over coals to heat.
