Rinse the quinoa thoroughly in a fine-mesh strainer to remove any bitterness.
Place the dry quinoa in a small pot over medium heat and toast for 2 minutes until it smells nutty and begins to pop.
Add 0.5 cup of water to the pot, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until water is absorbed.
While quinoa cooks, season the chicken breast evenly with sea salt, black pepper, garlic powder, and turmeric.
Heat the olive oil in a skillet over medium-high heat and sear the chicken for 6 to 7 minutes per side until golden brown and cooked through.
Steam the broccoli florets in a steamer basket for 4 to 5 minutes until they are bright green and tender-crisp.
Fluff the quinoa with a fork and transfer it to a serving bowl.
Slice the chicken into strips and place over the quinoa along with the steamed broccoli and sliced avocado.
Finish the bowl with a fresh squeeze of lemon juice for brightness.
