Prepare the Sauce: In a mixing bowl, whisk together honey, soy sauce, rice vinegar, and minced garlic until well combined. Set aside.

Make the Cornstarch Slurry: In a small bowl, combine cornstarch with water, stirring until smooth. Set aside.

Cook the Chicken: Heat vegetable oil in a large skillet over medium-high heat. Season chicken with salt and pepper, sauté for 5-7 minutes until fully cooked.

Stir-Fry the Veggies: In the same skillet, add more oil if needed, then add bell pepper, broccoli, and carrot. Stir-fry for 4-5 minutes until tender-crisp.

Combine Chicken and Veggies: Return chicken to the skillet, pour over honey garlic sauce, and stir for 1 minute to heat through.

Thicken the Sauce: Add cornstarch slurry, stirring quickly until sauce thickens for about 2 minutes.

Garnish and Serve: Remove from heat, serve hot garnished with green onions and sesame seeds. Pairs well with rice or noodles.
