Method
- In a large bowl, combine ground chicken, crumbled feta, diced red onion, chopped spinach, minced garlic, oregano, and lemon zest. Season with a small pinch of salt (the feta is already salty) and black pepper. Mix gently with your hands until just combined.
- Divide the mixture into 4 equal portions and shape into patties about 3/4-inch thick. Make a small indent in the center of each patty with your thumb to prevent doming.
- Heat olive oil in a large non-stick skillet or grill pan over medium heat for 2 to 3 minutes until hot.
- Place patties in the pan without touching each other. Cook undisturbed for 5 to 6 minutes until edges turn opaque. Flip carefully and cook another 5 to 6 minutes on the second side. Avoid pressing down on the patties.
- Check that internal temperature reaches 74°C (165°F) using an instant-read thermometer. Patties should feel firm and juices should run clear.
- Lightly toast buns or pitas while burgers rest for 1 to 2 minutes. Place each burger on the bottom bun and top with cucumber slices, tomato, red onion, and tzatziki sauce. Serve immediately.
Notes
Storage: Cooked burgers keep in the refrigerator for up to 3 days in an airtight container. Reheat in microwave for 45-60 seconds or in a skillet over medium-low heat for 2-3 minutes per side. Freezing: Freeze cooked or raw patties for up to 3 months. Place on a baking sheet to freeze solid, then transfer to freezer bags with parchment between patties. Thaw overnight before reheating. Make-ahead: Form raw patties up to 24 hours in advance and refrigerate covered. Substitutions: Ground turkey works well in place of chicken. Goat cheese can substitute for feta. Use large lettuce leaves instead of buns for low-carb option. Grilling: Cook on preheated medium-heat grill for 5-6 minutes per side.
