01 - Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until browned and cooked through, about 5-6 minutes. Drain excess fat if necessary.
02 - Add diced onion and minced garlic to the skillet. Sauté for 2-3 minutes until fragrant and onion is translucent.
03 - Stir in the Brussels sprouts and cook for 3-4 minutes, allowing them to caramelize slightly.
04 - Add soy sauce, Worcestershire sauce, smoked paprika, black pepper, and salt. Mix well to coat all the ingredients.
05 - Cover the skillet with a lid, reduce heat to medium, and cook for another 6-8 minutes until Brussels sprouts are tender but still slightly crisp.
06 - Remove lid, stir, and cook uncovered for a final 2 minutes to evaporate any excess moisture. Garnish with chopped parsley and a sprinkle of Parmesan cheese if desired. Serve hot.
