Best F&$king Grilled Chicken Sandwich

Why this recipe works

• By alternating layers of mayonnaise, crushed potato chips, a flavorful jalapeño-avocado sauce, lettuce, and tomato, this sandwich delivers a range of textures, from crisp and crunchy to soft, tender, and juicy.
• By pounding and quick-brining the chicken breasts, the meat cooks evenly and stays moist on the grill.
• Grilling bacon on the edge of the hot zone crisps it perfectly while reducing flare-ups.
