Rinse the quinoa under cold water to remove its natural coating, called saponin, which can taste bitter.

Combine the rinsed quinoa with water or broth in a pot. Bring to a boil, then reduce the heat and simmer for about 15 minutes until the quinoa is cooked and the liquid has been absorbed.

Fluff with a fork to separate the grains.

While the quinoa cooks, season the steak with olive oil, salt, and pepper.

Heat a grill or skillet over medium-high heat and cook the steak for approximately 4-5 minutes on each side for medium rare, or until it reaches your desired doneness.

Let it rest for a few minutes before slicing to allow the juices to redistribute.

In the same skillet used for the steak, stir-fry the mixed vegetables until tender but still crisp, about 3-4 minutes.

To assemble the bowl, place a generous serving of quinoa at the bottom.

Top it with slices of steak, the sautéed vegetables, and optional avocado slices.

Garnish with fresh herbs for an added touch of flavor and freshness.
