Rinse the brown basmati rice under cold water until clear, then combine with 0.5 cups of water in a small pot and bring to a boil.
Reduce heat to low, cover, and simmer the rice for 35-40 minutes or until water is absorbed and rice is tender.
While rice cooks, season the chicken breast on both sides with sea salt, black pepper, and garlic powder.
Heat avocado oil in a large skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the skillet to rest, then add the broccoli florets and sliced red bell pepper to the same pan with a splash of water, covering to steam for 3-4 minutes.
Slice the rested chicken into strips.
Assemble the bowl by layering the cooked rice, steamed vegetables, and sliced chicken.
Top with sliced avocado and drizzle the coconut aminos over the entire bowl before serving.
