First a good rinse is obviously needed. I then, generally do a quick saute in butter with garlic, s & p. Keep it simple until you figure out what you like about them, if anything. Think about very young asparagus.
My first experience came when I was hitching a ride to work, a woman stopped and gave me a bag she had foraged down the ways from our house. I gave them to the chef, he was happy. I never found any reason to spend serious money in the market for them.
We lived across the street from an asparagus field, so I was spoiled.
