Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with 1 teaspoon of olive oil, a pinch of sea salt, and a pinch of black pepper.
Spread the broccoli on the baking sheet and roast for 15-20 minutes until the edges are golden and tender.
While the broccoli roasts, season the chicken breast evenly with garlic powder and the remaining sea salt and black pepper.
Heat the remaining 1 teaspoon of olive oil in a skillet over medium-high heat.
Cook the chicken for 6-7 minutes per side, or until the internal temperature reaches 165°F.
Allow the chicken to rest for 5 minutes before slicing it into thin strips.
Assemble your bowl by placing the cooked quinoa at the base, followed by the roasted broccoli and sliced chicken.
Top with fresh avocado slices and a drizzle of lemon juice for a bright finish.
