This was pretty plain when I was done, and I stopped at 1.5 tbs of lemon juice because it was about to become too much. So I added 1/4 cup cilantro and a bit of basil to taste. It worked perfecty, and was very good. If you find your sauce too liquidy, boil off the liquid until the sauce sticks to the pasta and until there is none that sinks to the bottom. Although I like asparagus, I think something else, like broccoli or green pepper would work better in this recipe.
