Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Pat the chicken breast dry and season lightly with salt and pepper.
Coat the chicken evenly with almond flour, pressing gently to adhere.
Place the coated chicken on one side of the baking sheet.
In a small bowl, mix together orange juice, honey, soy sauce, minced garlic, grated ginger, and cornstarch until smooth to form the orange glaze.
On the other side of the baking sheet, toss the green beans with olive oil, salt, and pepper.
Bake the chicken and green beans in the preheated oven for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the green beans are tender and slightly crispy.
About 5 minutes before the chicken is done, brush the orange glaze over the chicken to allow it to set and become slightly sticky.
Remove from the oven and let the chicken rest for a couple of minutes before serving alongside the roasted green beans.
