A delicious chicken sandwich with a slice of pineapple and drizzled in a sweet teriyaki sauce. It's the perfect sandwich to make on the grill and sure to satiate your taste buds!
Place chicken in self-sealing plastic bag along with half of teriyaki sauce. Seal; marinate at least 1-2 hours, turning once or twice.
Remove chicken from bag. Discard marinade.
Grill chicken breasts over medium heat about 6-8 minutes on each side or until done.
Baste with remaining teriyaki sauce while cooking, 2-3 times.
Add sandwich buns and pineapple slices to grill the last few minutes while cooking chicken, turning once to lightly brown both sides.
Top each bun with lettuce, tomato, chicken breast, and finally with pineapple (optional).
