Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a small bowl, whisk together low sodium soy sauce, honey, minced garlic, grated ginger, and cornstarch slurry (mix the cornstarch with a small amount of water). Set aside.
Pat the chicken breast dry with a paper towel. Lightly dredge it in a thin layer of cornstarch for extra crispiness.
Heat olive oil in a skillet over medium-high heat. Sear the chicken breast on both sides until golden, about 2-3 minutes per side.
Transfer the chicken to the prepared baking sheet. Brush the chicken generously with the teriyaki sauce mixture.
Toss the green beans with a little olive oil, salt, and pepper. Arrange them around the chicken on the baking sheet.
Roast in the oven for 15-18 minutes, or until the chicken is cooked through and the green beans are tender with crispy edges.
Once done, drizzle any remaining sauce from the pan over the chicken and green beans, then sprinkle with sesame seeds.
Serve immediately and enjoy your delicious crispy teriyaki chicken with roasted green beans.
