Greek-Style Turkey Burgers

Ingredients

• 1 medium seedless cucumber
• 1 1/2 c. whole-milk plain Greek yogurt
• 2 Tbsp. olive oil, plus more for brushing
• 1 Tbsp. chopped fresh dill
• 1 Tbsp. fresh lemon juice
• 1 small garlic clove, finely chopped
• 1 tsp. kosher salt
• Black pepper, to taste
• 1 red onion
• 2 lb. ground turkey
• 1 large egg yolk
• 1 tsp. dried oregano
• 6 pitas
• 1/2 head Boston lettuce
• 1 4-ounce package crumbled feta cheese (about 3/4 cup)
• Potato chips, for serving

Directions

1. Preheat the oven to 250 ̊. For the tzatziki: Grate 1⁄2 cucumber onto a clean kitchen towel and wring dry.
2. Combine the grated cucumber with the yogurt, olive oil, dill, lemon juice, garlic, 1/2 teaspoon salt and a few grinds of pepper in a medium bowl. Refrigerate while you make the burgers.
3. For the burgers: Grate 1/2 red onion and combine with the turkey, egg yolk, oregano, remaining 1/2 teaspoon salt and a few grinds of pepper in a large bowl. Mix with your hands, then form into six 1/2-inch-thick patties. Place on a sheet of parchment.
4. Put the pitas on a baking sheet and keep warm in the oven.
5. Heat a large cast-iron or other nonstick skillet over medium-high heat and brush with olive oil. Add 3 patties and cook until no longer pink in the center, 4 to 5 minutes per side. Transfer to a separate baking sheet and keep warm in the oven. Wipe out the pan, brush with more olive oil and repeat with the remaining patties.
6. Cut off the tops of the pitas. Chop the remaining 1/2 cucumber and slice the remaining 1/2 red onion. Spread some tzatziki inside each pita. Fill each with lettuce, a patty, cucumber, red onion and feta. Serve with chips.
