Grilled Teriyaki Chicken Sandwiches

These sandwiches are super easy and really good!  The pineapple really adds a good touch to the flavor of this meal.  It's a great summer go to meal for the grill.

Grilled Teriyaki Chicken Sandwiches

2 chicken breasts
1/2 bottle teriyaki marinade (I used Mrs. Dash Spicy Teriyaki with no salt added & no MSG)
2 slices of pineapple (cored and peeled)
2 slices swiss cheese
2 crispy hamburger style buns (a crispy bun works better, too soft and the bread gets mushy)
2 tbsp butter
Using a meat pounder, flatten chicken breasts to preferred thickness.  Place chicken and marinade in large ziploc bag, allow to marinade in refrigerator at least 1 hour.  Grill chicken until no longer pink, about 10-15 minutes.  Brush pineapple slices with melted butter.  Grill pineapple about 5 minutes, until nice grill marks show.  Top each chicken breast with a slice of cheese and allow cheese to melt.  Toast bun then spread with a little more teriyaki sauce.  Layer chicken then pineapple on bun.  Serve with grilled veggies.
