This burger is a Mediterranean twist on the classic American favorite. The patty is made with ground lamb, seasoned with garlic, oregano, and feta cheese. It's topped with a refreshing tzatziki sauce, made with Greek yogurt, cucumber, and dill. Add some sliced red onion and crumbled feta cheese for extra flavor and texture. Serve it on a toasted bun or wrapped in a pita for a delicious and healthy meal.
