Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Mince the garlic and grate the fresh ginger.
In a small bowl, whisk together the tamari, honey, minced garlic, and grated ginger to create the teriyaki sauce.
Heat sesame oil in a large skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-6 minutes until golden brown and cooked through.
Add the broccoli florets to the skillet with a splash of water, covering for 2 minutes to steam until vibrant green.
Pour the teriyaki sauce over the chicken and broccoli, stirring for 1 minute until the sauce thickens and coats everything.
Divide the cooked brown rice into meal prep containers and top with the chicken and broccoli mixture.
Garnish with sesame seeds.
To reheat at work, microwave for 1-2 minutes or add a tablespoon of boiling water before heating to keep the rice moist.
