Pat the chicken breast dry with a paper towel and toss in a bowl with the cornstarch, sea salt, and black pepper until evenly coated.
In a small jar or bowl, whisk together the honey, tamari, and minced garlic until the honey is fully incorporated.
Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and sear until golden brown and crispy on all sides, approximately 6 to 8 minutes.
While the chicken cooks, steam the broccoli florets in a steamer basket for 4 to 5 minutes until they reach a vibrant green and tender-crisp texture.
Lower the skillet heat to medium and pour the honey-garlic sauce over the chicken, stirring constantly for 1 to 2 minutes until the sauce becomes a thick, glossy glaze.
Divide the cooked jasmine rice into bowls, then top with the glazed chicken and steamed broccoli.
Finish the dish with a sprinkle of sesame seeds and sliced green onions for a fresh crunch.
