Add chicken breast cubes to gallon sized zippered bag. Combine remaining ingredients in a small bowl. Pour over chicken and seal bag. Squish around to evenly coat chicken. Let marinate at least 4 hours (up to 24 hours).
Preheat grill to medium-high (425degF).
Add marinated chicken cubes to skewers (approximately 8 to each skewers). Discard marinade.
Grill for 10 minutes then spin to other side and grill another 10 minutes. Remove from grill. Either serve on skewers or remove from skewer before serving.
