Clean brussels sprouts by removing outer layer of leaves and trimming stems. Cut each sprout into 1/4" thick slices.

Heat oil over medium-high heat in a large pan. Add garlic and cook untill softened. If using chorizo and onion add them in now.

Add sprouts, cook 2 to 3 min. until oil is absorbed.

During this time sprouts will begin to brown. Turn heat down and cook for about another 5 min., stirring occationally, until sprouts become browned and slightly crispy. Season with salt and pepper.
