"This Peruvian Style Grilled Chicken is a recipe I back-hacked from the awesome chicken and green sauce they serve at Pio Pio in NYC. The basics are simple: butterflied chicken with a vinegar and spice rub gets slow-cooked on the grill, followed by a quick stay directly over the coals to crisp the skin. It comes out tender and juicy and goes perfectly with a simple spicy and cream sauce made with jalapeños and aji amarillo peppers."
