In a mixing bowl, combine olive oil, garlic powder, paprika, salt, and black pepper. Add the chicken breasts and coat them evenly. Let marinate for at least 15 minutes.

Preheat the grill to medium-high heat. Grill the chicken for about 6-7 minutes on each side or until fully cooked and internal temperature reaches 165°F (75°C).

While the chicken is grilling, steam the broccoli florets in a steamer for about 5-7 minutes until bright green and tender-crisp.

In a mixing bowl, combine Greek yogurt, minced garlic, lemon juice, dried dill, salt, and black pepper. Whisk until smooth and creamy.

Slice the grilled chicken into strips. In bowls, layer the steamed broccoli and sliced chicken. Drizzle with creamy garlic sauce and add optional toppings if desired.
