1 lb. frozen petite Brussels sprouts Heat oven to 450 degree F. Layer frozen Brussels sprouts on glass baking dish in single layer. Cook until roasted--about 20 minutes. Stir halfway through cooking. (You can thaw them first in the fridge and broil them and they take even less time.) Drizzle 2-3 Tbsp. balsamic vinegar over Brussels sprouts and serve. Makes about 4 servings. Jeff Novick recipe.
