Place plastic wrap on top of each chicken breast and pound on it with a kitchen mallet until it is about 1/2-inch thick. It doesn't matter if it's a little larger than your bun, it shrinks while cooking.
Place the chicken breasts in a sealed container, and the pineapple slices in another. Divide the teriyaki marinade between the two, covering each with enough teriyaki marinade. Refrigerate for 4-6 hours. Starting this in the morning is perfect.
Pre-heat your grill or BBQ to medium-high heat.
Place the chicken on the lower rack of your BBQ grill. Grill for around 6-7 minutes per side. Around 3/4 of the way through, add the pineapple slices to the top rack of your BBQ if you have one. They tend to not burn up on this level.
When the chicken is cooked and the pineapple are warm and have grill marks, place a Swiss cheese slice on each chicken breast to melt.
If you desire, toast your hamburger buns now.
Slather the mayo on the buns, then place the chicken breast on the bottom bun. Place 2 tomato slices, followed by 2 pineapple slices on each chicken breast, followed by the shredded lettuce and the bun top.
