Place cubed chicken breasts in a large resealable plastic bag. Whisk together soy sauce, maple syrup, and sriracha sauce. Pour over the top of the chicken and massage into the chicken. Marinate for at least 4 hours in the refrigerator.
Once chicken is done marinating, soak wooden skewers in water for 10 minutes. Then skewer the chicken pieces on to the skewer. We had about 6 skewers with maybe 6-7 pieces of chicken on each skewer.
Turn your outdoor grill on high (or you can use an indoor grill or your stovetop) and grill chicken until thoroughly cooked through.
