Heat the olive oil in a large skillet over medium heat. Add the onion and garlic and cook until softened, about 5 minutes.
Add the cauliflower rice and stir to combine with the onion and garlic. Cook for an additional 5 minutes or until the cauliflower is tender.
Season with cayenne pepper, salt, and pepper to taste. Stir to combine and cook for an additional 2 minutes before serving. Enjoy!.
