"I serve this without the roll for a great low-carb meal. If you decide to use a roll, drain the Pico de Gallo before placing on top of the burger to prevent the bun from getting wet. Fresh cilantro is a must for the Pico de Gallo. While you may choose to use a little cooking spray, it is not necessary as the burgers, at first a little sticky, will firm up as they cook." — Peach822
