Cook the rice according to package instructions using chicken broth.
In a large skillet, heat olive oil over medium heat and cook the chicken.
Season the chicken with garlic powder, salt, and pepper while cooking.
Once cooked, remove the chicken from the skillet and set aside.
Add broccoli to the same skillet and sauté until tender.
Once broccoli is cooked, return the chicken to the skillet.
In a separate bowl, mix heavy cream and shredded cheddar cheese until smooth.
Pour the cheese mixture into the skillet and stir to combine.
Finally, fold in the cooked rice and mix gently.
Taste and adjust seasonings if necessary, then serve warm.
