"You know that saying, 'The simplest things in life are best?'" Iron Chef Alex Guarnaschelli asks. "That's what this cheeseburger is — bite after bite after bite." She's talking about the no-frills cheeseburger (pictured above) from New York City's Sister Midnight restaurant, which brings together a super-moist burger blanketed with creamy America cheese and traditional lettuce-tomato-onion fixings. Prefer to skip the meat? Alex is also keen on Sister Midnight's veggie burger, made hefty with fresh cauliflower, beets and quinoa and deep-fried until crispy.
