Place chicken in a large ziplock bag. Add garlic, sriracha sauce, ginger, vinegar, soy sauce, pepper, brown sugar and (optional) bay leaves to the bag, seal, and slosh around to combine ingredients. Chill for 2 hours or up to 24 hours.
Drizzle oil into a medium-large skillet. Add chicken and marinade to the pan and cook chicken for 5-8 minutes, then turn over and cook another 5-8 minutes until chicken is cooked though.
Serve chicken and sauce over rice and garnish with sliced green onions.
Notes
Serve over rice with a side of roasted veggies for a complete meal!
