Mince the garlic and finely chop the fresh parsley.
Season the chicken breast on both sides with sea salt, black pepper, and dried oregano.
Heat half of the extra virgin olive oil in a skillet over medium-high heat.
Place the chicken in the skillet and cook for 6-8 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest for 5 minutes before slicing.
In the same skillet, add the remaining oil, broccoli florets, and cherry tomatoes, sautéing for 4-5 minutes until the vegetables are tender-crisp and tomatoes begin to blister.
In a medium bowl, combine the cooked quinoa with fresh lemon juice, minced garlic, and chopped parsley, fluffing with a fork to incorporate.
Assemble the bowl by layering the lemon-herb quinoa at the base, topped with the sliced chicken and sautéed vegetables.
