Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the avocado oil, salt, and pepper on the prepared baking sheet.
Roast the broccoli for 15 to 20 minutes until the edges are golden and slightly charred.
Rinse the quinoa under cold water and place in a small saucepan with 2/3 cup of water.
Bring the quinoa to a boil, then reduce heat to low, cover, and simmer for 15 minutes until water is absorbed.
Season the chicken breast with salt, pepper, and your favorite dried herbs like oregano or thyme.
Heat a grill pan or outdoor grill over medium-high heat and lightly coat with the remaining avocado oil.
Grill the chicken for 6 to 8 minutes per side until the internal temperature reaches 165°F.
Let the chicken rest for 5 minutes before slicing it into strips.
Fluff the quinoa with a fork and serve it in a bowl topped with the sliced chicken and roasted broccoli.
