Rinse the white basmati rice under cold water until clear, then combine with 0.5 cups of water in a small saucepan, bring to a boil, and simmer covered for 15 minutes.
In a small bowl, whisk together the tamari, honey, minced garlic, and grated fresh ginger to create the teriyaki glaze.
Cut the chicken breast into 1-inch bite-sized pieces and season evenly with the sea salt and black pepper.
Heat the avocado oil in a large skillet over medium-high heat and sauté the chicken pieces until golden brown and cooked through, about 6-8 minutes.
While the chicken cooks, place the broccoli florets in a steamer basket over boiling water and steam for 4-5 minutes until vibrant green and tender-crisp.
Pour the teriyaki glaze into the skillet with the chicken and toss constantly for 1-2 minutes until the sauce thickens into a glossy coating.
Fluff the cooked rice with a fork and stir in the toasted sesame oil and sesame seeds for a nutty aromatic finish.
Plate the glazed chicken alongside the sesame rice and steamed broccoli for a clean, balanced meal.
