Preheat your oven to 425°F.
In a small bowl, combine lemon juice, lemon zest, minced garlic, olive oil, dried oregano, dried thyme, salt, and pepper to create the marinade.
Pat the chicken breast dry and lightly coat it with almond flour. Then, spoon the marinade over the chicken, ensuring it is evenly covered.
Place the chicken breast on a baking sheet lined with parchment paper. In a separate bowl, toss the zucchini, red bell pepper, and broccoli florets with a pinch of salt, pepper, and a drizzle of olive oil if desired.
Arrange the vegetables around the chicken on the baking sheet. Roast in the preheated oven for about 20-25 minutes, or until the chicken is cooked through and the vegetables are tender with crispy edges.
While the chicken and vegetables are roasting, warm the cooked quinoa if needed.
Once done, slice the chicken breast and assemble your power bowl by layering the quinoa, roasted vegetables, and sliced lemon herb chicken.
Finish with an extra squeeze of lemon if desired, and enjoy your vibrant, nutritious power bowl warm.
