These Olive and Feta Lamb Burgers are a delicious twist on the classic beef burger. The juicy lamb patties are flavored with tangy feta cheese, briny olives, and aromatic herbs. They are grilled to perfection and served on a toasted bun with fresh lettuce, tomato, and a creamy tzatziki sauce. These burgers are packed with flavor and make a great option for a summer barbecue or a casual dinner.
