Ingredients:

  • 1.5 lbs ground beef (80% lean / 20% fat)
  • 1/2 cup crumbled feta cheese
  • 3 tbsp fresh parsley, finely chopped
  • 1 tbsp fresh oregano, minced
  • 2 cloves garlic, minced
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 1 tsp dried oregano
  • 4 brioche or ciabatta buns
  • 4 slices red onion, thinly sliced
  • 4 leaves fresh spinach or arugula
  • 4 tbsp Tzatziki sauce

Instructions:

  1. In a large bowl, combine the ground beef, crumbled feta, fresh parsley, fresh oregano, minced garlic, salt, pepper, and dried oregano. Gently mix with your hands until just combined; divide into 4 equal portions and shape into patties about 1 inch thick.
  2. Preheat grill to medium-high heat. Place the patties on the grate and grill for 4–5 minutes per side until a deep, mahogany-colored crust forms.
  3. Remove burgers from the grill once they reach an internal temperature of 145°F (63°C). Let the patties rest for 5 minutes.
  4. Assemble the burgers by placing the patty on a bun and topping with Tzatziki sauce, red onion, and spinach or arugula.
