Make the marinade.
In a medium bowl, whisk together the soy sauce, brown sugar, oil, ginger, lime juice, garlic, and Siracha.
Pour the marinade in a reusable freezer bag or marinator with the chicken.
Press out the air and seal shut.
Place the bag in a bowl and refrigerate for at least 1 hour or overnight.
Preheat the grill to high heat.
Carefully brush the grill grates with oil to prevent the chicken from sticking.
Place the chicken on the hot grill and discard the marinade.
Cook for 5 to 7 minutes per side, until browned and cooked through, the internal temperature should be 165 degrees Fahrenheit.
