Heat 3 tablespoons of oil in a large nonstick skillet over medium-high heat. Add the chicken in a single layer and cook both sides for 2-3 minutes until browned and cooked through. Remove to a plate.
Add the remaining 1 tablespoon of oil to the skillet. Add the garlic and saute for 30-60 seconds.
Pour in the honey garlic sauce and bring to a simmer. Let the sauce cook for 30-60 seconds until it starts foaming. Return the chicken to the skillet and toss to coat the chicken. Serve immediately.
