In a large skillet, heat the pan over medium heat and add the ground beef. Cook for about 5–7 minutes, stirring occasionally, until the beef is browned and no longer pink. Then drain any excess grease.

Stir in the frozen cauliflower, garlic powder, salt, and pepper. Cook for an additional 5–7 minutes, stirring frequently, until the cauliflower is tender.

Sprinkle shredded cheddar cheese evenly over the mixture. Reduce the heat to low, cover the skillet, and let it sit for about 2–3 minutes until the cheese melts.

Remove from heat and add any optional toppings like jalapeños, bacon, or sour cream. Serve immediately, garnished with green onions.
