Butterflied Portuguese Chicken with Lemon Mayonnaise is a flavorful and juicy grilled chicken dish. The chicken is marinated in a blend of Portuguese spices, garlic, and lemon juice, which infuses it with a tangy and aromatic flavor. The chicken is then grilled to perfection, resulting in a crispy and charred exterior and a tender and moist interior. It is served with a zesty lemon mayonnaise that complements the flavors of the chicken beautifully. This dish is perfect for a summer barbecue or a casual weeknight dinner.
