Rinse the jasmine rice in cold water until the water runs clear. Combine with 350ml of water in a pot, bring to a boil, then reduce to low, cover, and simmer for 15 minutes.
While rice is cooking, season the cubed chicken breast with garlic powder, onion powder, smoked paprika, salt, and black pepper.
Heat olive oil in a large non-stick skillet over medium-high heat (approx 190°C).
Add chicken to the skillet in a single layer. Sear for 6-8 minutes, turning occasionally, until the internal temperature reaches 74°C (165°F).
Steam the broccoli florets for 4-5 minutes until tender-crisp and vibrant green.
In a small mixing bowl, whisk together the BBQ sauce, honey, soy sauce, and sriracha until emulsified.
Reduce the skillet heat to low. Pour the sauce over the chicken and toss constantly for 1-2 minutes until the glaze is thickened and glossy.
Portion 150g of cooked rice, 75g of steamed broccoli, and 150g of glazed chicken into four containers or serving plates.
