Whisk the tamari, honey, rice vinegar, minced ginger, minced garlic, sambal oelek, arrowroot powder, and water in a small bowl until the starch is fully dissolved.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the cubed chicken breast and tofu to the skillet, searing for 5 to 6 minutes until the chicken is cooked through and the tofu has developed a golden, crisp exterior.
While the protein cooks, steam the broccoli florets in a steamer basket for 3 to 4 minutes until they reach a bright green, tender-crisp texture.
Pour the prepared sauce into the skillet with the chicken and tofu, tossing constantly for 1 minute as the sauce bubbles and thickens into a glossy glaze.
Remove from heat and drizzle with toasted sesame oil.
Assemble the bowl by placing the warm brown rice at the base, topping with the glazed chicken and tofu, and adding the steamed broccoli on the side.
Garnish with sliced green onions and sesame seeds before serving.
