Pat the chicken breast dry with a paper towel and season both sides evenly with sea salt, black pepper, and garlic powder.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 6-7 minutes per side, or until the internal temperature reaches 165°F and the exterior is golden brown.
While the chicken cooks, steam the broccoli florets and sliced red bell peppers until tender-crisp, about 4-5 minutes.
Remove the chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
In a portable bowl or container, layer the cooked quinoa at the base.
Top the quinoa with the steamed broccoli, bell peppers, and sliced chicken.
Add the fresh avocado slices to the bowl and drizzle the entire dish with lemon juice just before serving.
