Bring a skillet or grill pan sprayed with nonstick spray to medium-high heat. Place the pineapple in the skillet and cook until slightly blackened and caramelized, about 3 minutes per side. Set aside to cool.
Add patty to the skillet and cook until hot, about 2 minutes per side. Place cheese slice on top of the patty while still in the skillet.
Place the patty on the bottom 1/2 of the bun, and top with teriyaki sauce. Add pineapple, tomato, and lettuce.
Spread the mayonnaise on the top half of the bun, and finish your burger off with the bun's top 1/2. Now CHOMP!
