Cut the chicken breast into bite-sized pieces and pat them dry with a paper towel.
In a medium bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat avocado oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through, about 5-7 minutes.
Remove the chicken from the pan and add the broccoli florets with a tablespoon of water, covering with a lid for 2 minutes to steam until bright green.
In a small jar, whisk together the orange juice, orange zest, coconut aminos, minced ginger, minced garlic, and red pepper flakes.
Return the chicken to the skillet, pour the sauce over the ingredients, and stir for 1-2 minutes until the glaze thickens and coats everything beautifully.
