Rinse the Brussels sprouts with water and sliced into halves.
Heat a skillet over medium-high heat. Add olive oil and let it heat for 1 or 2 minutes. Sauté the garlic a few times, add the Brussels sprouts, salt and pepper. Stir to combine well.
Let the sprouts cook undisturbed for approximately 5-7 minutes, or until the undersides become beautifully golden and crisp. Occasionally stir to ensure even cooking. Lower the heat, place a lid on the skillet, and allow the Brussels sprouts to simmer for another 5-7 minutes, or until they become tender and can be easily pierced with a fork
Remove from the skillet and serve immediately. Garnish with fresh parsley if desired.
