Salmon is rich in omega-3 fatty acids, which are known to lower cholesterol, and it is about as healthy as fish can get. But that is really a side benefit to this great-tasting main-course salad. I would happily serve it any day of the week and for any occasion. The warm orzo salad, with crunchy pine nuts, fresh basil, tender spinach, and tangy feta, is also good on its own. The salmon can also be cooked in a ridged grill pan.
