In a small bowl, whisk together the honey, soy sauce, minced garlic, and red pepper flakes until well combined.
Season the cubed chicken with salt and black pepper.
Heat the olive oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook for 6 to 8 minutes, stirring occasionally, until browned and cooked through.
Remove the chicken from the skillet and set aside on a plate.
Add the green beans to the same skillet with two tablespoons of water; cover with a lid and steam for 3 to 4 minutes until tender-crisp.
Return the chicken to the skillet and pour the honey-garlic sauce over the chicken and green beans.
Cook for an additional 2 to 3 minutes, tossing constantly, until the sauce reduces to a thick glaze that coats the ingredients.
Serve immediately.
