１Place the salmon slices in the marinade for approx. one hour. Turn them over several times while marinating. ２Dip the tomato in boiling water, then soak in cold water to peel the skin off. Cut the tomato in half horizontally, remove the seeds and cut into 5mm cubes. Roughly mince the basil leaves, and cut the lemon into wedges. ３Drain the salmon slices and place them on a baking pan. Preheat an oven to 200℃ and grill the salmon in it for approx. 20 minutes. Baste the salmon with the oil drippings from the pan over the salmon several times while grilling. ４To make the sauce, melt the butter in a small pan and add the tomato and basil prepared in 2. Season with the lemon juice, salt and pepper. ５When the salmon is done, place it on a serving dish along with the lemon wedges and parsley. Pour the sauce over the salmon.
