It seems that we end up eating a variation of this dish almost every week. I love the Greek flavors on the salmon, and when it is smoked in the Traeger grill with cherry-wood pellets, it is hard to beat. Salmon has always been a favorite of mine, not just because of my last name, and Mary Jo loves it as well. Make the Tzatziki sauce at least a few hours in advance so the flavors can meld together. The feta salad can also be made in advance.
