Marinate the chicken in soy sauce, minced garlic, and lemon juice for at least 30 minutes.

Preheat the grill to medium-high heat.

Cook the marinated chicken for 6–7 minutes per side, or until the internal temperature reaches 165°F.

While the chicken is grilling, warm olive oil in a skillet over medium heat and sauté the broccoli for 5–7 minutes until tender but still vibrant; season with salt and pepper.

In a small saucepan over low heat, combine heavy cream, the remaining minced garlic, soy sauce, and any leftover marinade that has been brought to a boil and simmer gently until warmed through and slightly thickened.

After the chicken rests briefly, slice it and assemble bowls by layering sautéed broccoli at the base, topping with sliced chicken, and drizzling the creamy garlic sauce over everything; serve immediately.
