Slice a thick chicken breast into thin, 3-oz filets. Pat them dry with a paper towel and then season with the salt, pepper, onion powder, garlic powder, italian seasoning, and paprika.
Heat the olive oil in a pan over medium-high heat and place the chicken breasts in seasoned side down. Cook the breasts 4-5 minutes per side, adjusting the heat as necessary. You may also place a lid over the chicken and cook for just 3 minutes per side.
Transfer the chicken to a serving dish and return your pan to the stove. Chop THAWED broccoli into chunky florets and toss with seasoned salt, pepper, and olive oil over high heat. Cook until the broccoli has browned grill marks all over.
Reduce the heat to low and push the broccoli into the center of the pan. Sprinkle the cheddar cheese and allow it to melt over the broccoli. You may use a lid to help melt the cheese fast.
Transfer the cheesy broccoli to the serving dish with the chicken. Return your pan to the stove for a third time. In the pan, stir together the cauliflower rice, salt, pepper, onion powder, and parsley. Cook and stir over high heat until golden.
Reduce the heat to low and melt the butter into the rice. Stir until all the rice is coated.
Serve the buttery rice alongside the chicken and broccoli and enjoy.
