In a small bowl, make your "marinade". Combine oil, garlic, honey, soy sauce, apple cider vinegar, salt and pepper. Whisk well until combined.
Pour marinade over chicken cubes and toss to combine. Allow to marinate for at least 5 minutes.
Cook chicken cubes with sauce on medium heat until marinade is reduced and chicken is cooked through, usually about 15 minutes. Chicken will have a "sticky" sauce coating when finished. Make sure to move chicken around regularly to prevent burning, and reduce heat to low at any point if needed to prevent burning.
