Heat the olive oil in a large skillet over medium-high heat.
Lightly season the chicken cubes with salt and black pepper.
Add the chicken to the hot skillet and cook for 3–4 minutes until browned on one side.
While the chicken cooks, whisk together the honey, soy sauce, garlic, and red pepper flakes in a small bowl.
Flip the chicken pieces and pour the sauce into the skillet.
Toss everything together until the chicken is evenly coated.
Continue cooking for another 4–5 minutes, stirring occasionally, until the 15 Minute Honey Garlic Chicken is fully cooked and the sauce thickens into a glossy glaze.
Serve immediately over steamed rice and garnish with green onions, sesame seeds, chopped peanuts, and a squeeze of fresh lime if desired.
