Start a grill or preheat broiler. Brush both sides of salmon with lemon juice. Grill for 5 to 6 minutes per side, turning once, until salmon flakes when prodded with the tines of a fork.

Meanwhile, in a bowl, combine shallots, tarragon, yogurt, tomato, and parsley. Mix well.

When salmon steaks are done, arrange on dinner plates and spoon some of the tarragon sauce alongside.
