Preheat your oven to 400°F (200°C).
Toss the broccoli florets with half of the olive oil, salt, and pepper on a parchment-lined baking sheet.
Roast the broccoli for 15-20 minutes until the edges are crispy and tender.
While broccoli roasts, season the turkey breast with salt, pepper, and a pinch of garlic powder.
Heat the remaining olive oil in a non-stick skillet over medium-high heat.
Sear the turkey breast for 5-7 minutes per side, or until the internal temperature reaches 165°F.
Remove the turkey from the pan and let it rest for 3 minutes before slicing.
In the same pan, briefly sauté the minced garlic until fragrant, about 30 seconds.
Fluff the pre-cooked quinoa and place it in a bowl.
Top the quinoa with the roasted broccoli and sliced turkey, then drizzle with fresh lemon juice and the toasted garlic oil from the pan.
