Creating these Grilled Chicken & Broccoli Bowls is simple with the following steps:

1. Prepare Chicken: Start by patting the chicken breasts dry with paper towels. This helps them grill well.
2. Season Chicken: In a bowl, mix the chicken with olive oil, garlic powder, salt, and pepper. Coat the chicken breasts evenly.
3. Grill Chicken: Preheat a grill or grill pan over medium-high heat. Grill the chicken for about 6-7 minutes on each side, or until the internal temperature reaches 165°F (75°C). Once cooked, remove from the grill and let rest for 5 minutes.
4. Cook Broccoli: While the chicken is resting, steam the broccoli florets until bright green and tender, around 3-4 minutes.
5. Make Creamy Garlic Sauce: In a small saucepan, heat a tablespoon of olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant. Add the heavy cream, lemon juice, salt, and black pepper. Stir continuously until the sauce thickens slightly, about 3-4 minutes. Remove from heat and stir in grated Parmesan cheese.
6. Slice Chicken: After resting, slice the grilled chicken into thin strips.
7. Assemble Bowls: In serving bowls, start with a base of cooked rice or quinoa. Add top with steamed broccoli and sliced chicken.
8. Drizzle Sauce: Generously pour the creamy garlic sauce over the chicken and broccoli.
9. Garnish: Optionally, sprinkle with extra Parmesan and herbs for added flavor.

Following these steps ensures your Grilled Chicken & Broccoli Bowls will turn out beautifully every time.
