Steps
1. Begin by cutting the chicken breast into bite-sized pieces and seasoning with salt, pepper, and red pepper flakes if using.
2. Heat the olive oil in a skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant.
3. Add the chicken pieces to the skillet and cook for 5-7 minutes until browned and cooked through.
4. Add the broccoli florets to the skillet, stirring well to combine. Cover and cook for an additional 3-4 minutes until the broccoli is tender but still vibrant green.
5. Drizzle the lemon juice over the chicken and broccoli, and toss to coat. Remove from heat.
6. Serve hot, garnished with grated Parmesan cheese if desired.
