Prep Chicken: Cut 1 pound boneless skinless chicken breasts into 1-inch pieces, set aside.
Make Sauce: In a medium saucepan, whisk together 1 cup water, ½ cup soy sauce, 4 tablespoons brown sugar, 2 teaspoons garlic, 1 teaspoon sesame oil, 1 teaspoon honey and ½ - 1 teaspoon fresh ginger. Bring to a simmer. In a small bowl, whisk together ¼ cup cold water and 2 tablespoons cornstarch. Add to saucepan; whisk to combine. Remove from heat when it reaches your desired thickness - remember it will thicken more as it cools slightly.
Cook Chicken: Bring a large cast iron skillet to medium-high heat. Add 2 teaspoons extra virgin olive oil and swirl to coat the pan. Add chicken and season lightly with a little kosher salt and ground black pepper. Move chicken around pan until it reaches 155℉. Add the sauce to the skillet of chicken (feel free to add a little at a time - you may have a little leftover). Stir to combine. Let simmer gently until chicken has fully cooked. Add 2 cups steamed broccoli and toss to combine.
Serve: Enjoy with sesame seeds sprinkled on top over a bed of rice of your choice!
Notes
Teriyaki: if you want to make this even easier, skip the homemade teriyaki sauce and simply use store-bought from the grocery store. Whatever works best for you!
Storage: store leftovers in an airtight container in the refrigerator for up to 3 days.
