I added the manchego cheese. I couldn't help it. If you cannot find good quality fresh asparagus I suggest Trader Joe's frozen asparagus tips for this recipe. Use the best olive oil you can find (most expensive doesn't always indicate the best quality). From Vegetarian: Best Ever Recipe Collection.
This is a recipe that I got from a vegetarian cookbook and made a few modifications to. We have fallen for this dish and now make it a few times a month. My two year old also loves it. We tried it out on some non-vegetarians and they all loved it.
