Red Robin Teriyaki Chicken Burger

"Menu Description: "A premium charbroiled chicken breast with sweet teriyaki sauce, grilled pineapple, Swiss cheese, lettuce, tomatoes and mayo. Why did the chicken cross the Pacific? Now you know." You're out there on the front line hanging over the grill. The smoke's in your eyes, the hair on your forearm is singed, and your sunburn is heading toward 2nd degree. But you don't care, because it's Saturday and you still get all of Sunday to heal. So whip out some chicken and grab the mallet - it's time to pound the flesh for this sweet chicken sandwich. With the kitchen mallet in hand, not only will you have an opportunity for further heroic injury, but you'll also be able to pound the chicken breast to a uniform thickness that works best when building sandwiches. The sweet and salty flavors of the custom secret teriyaki marinade go perfectly with the grilled pineapple and Swiss cheese (this recipe is for one sandwich but you'll have enough teriyaki marinade to make several sandwiches). Just be sure to watch the pineapple and chicken carefully while over the flames, since the teriyaki marinade has sugar in it and could cause charring from nasty flare-ups. Those small fires, while exciting, are just not good for your food. Source: "Top Secret Restaurant Recipes 2" by Todd Wilbur...."
