Trim any excess fat from the chicken breasts and cut them into approximately 1‑inch bite-sized pieces; set aside.
In a medium mixing bowl combine 3 tablespoons soy sauce, 2 tablespoons honey, 1 tablespoon vegetable oil, the juice of 1 lime, and 1 minced garlic clove. Stir until combined.
Season the marinade with salt and black pepper to taste, keeping in mind the soy sauce is salty.
Add the chicken pieces to the bowl and toss thoroughly so each piece is coated in the marinade.
Cover and refrigerate the chicken to marinate for at least 1 hour.
Preheat a grill or grill pan to medium-high heat. Oil the grate or pan lightly if needed.
Grill the marinated chicken pieces for about 4–5 minutes per side, or until juices run clear and the internal temperature reaches 165°F (74°C).
Remove from heat and let rest briefly before serving.
