This makes for a quick and flavorful meal. Just marinate the chicken earlier in the day (I have marinated it for only 1 hour and it was still very flavorful) and pop it on the grill for a quick dinner. I like to serve this over brown rice. You could also grill some veggies. Enjoy! Prep time does not include marinating.
Combine the teriyaki sauce, lemon juice, garlic and sesame oil in a large ziploc bag and add the chicken. Shake to coat. Place in the refrigerator for 1-12 hours to marinate, turning every so often.
Preheat grill on medium-high heat and lightly oil the grill grate (before it gets too hot).
Remove chicken, discarding marinade, and place on the grill. Grill for about 6-8 minutes on each side, or until juices run clear. (This could take even less time depending on the thickness of your chicken breasts.)
