1 lb ground turkey (I use 93% fat free)
3 tbsp Greek yogurt (I use 0% fat)
1-1/4 tsp Greek seasoning (try my favorite blend, from The Spice House)
1 Tbsp minced flat-leaf parsley
1/4 tsp fresh black pepper
For the sauce:
1/4 cup Greek yogurt
1 Tbsp mayonnaise
2 tbsp crumbled feta cheese
1/4 tsp lemon zest
A pinch of Greek seasoning
Fresh black pepper, to taste
In a large mixing bowl, combine turkey, 3 Tbsp Greek yogurt, 1-1/4 tsp Greek seasoning, parsley and black pepper. Mix with your hands, until all ingredients are combined, but do not overmix. Divide the mixture into four equal portions, and form each portion into a burger. Set the burgers aside (at room temperature).
In another bowl, combine all of the sauce ingredients, mashing the feta with the back of a spoon to incorporate it into the yogurt, and set aside at room temperature.
Spray your grill or stovetop grill pan with olive oil or canola spray and heat the grill to high-medium temperature (450-500F on a gas grill), or if you prefer, heat the grill first and then brush lightly with olive oil.
Grill the burgers for approximately 7 minutes, flip, and cook for an additional 4-5 minutes. To check for doneness, take one burger off the grill and use an instant-read thermometer; burgers should be 165F, so take them off when they're 160F and let sit, covered lightly with foil, for 5 minutes before serving. The temperature will continue to climb, and though you think the burgers will be dry and overcooked, the yogurt will keep them moist.
Serve topped with yogurt and feta sauce.
