this is a simple easy recipe and in my opinion one of the best ways to eat asparagus. fresh asparagus is the only important ingredient. take a zip lock bag and put the asparagus in. pour in a mixture of 3/4 soy sauce 1/4 balsamic vinegar--enough to cover most of the asparagus. close the bag and squeeze out all the air. let this marinate for at least 20 min and less than 12 hours. toss those babies on the grill--perpendicular to the grate. grill until slightly blackened--not burned. it goes with any other grilled dish.
