If you can find some scapes*, I'd sautee lightly in butter and evoo, and puree them hard and add this to your sauce. If the puree comes out a tad stringy, strain it. IF asparagus is still looking good, go for that as one of your in season veggies as well. Fresh basil should be abundant too. I'd go with an aglio/olio type primavera, but that's me. Not that you would skimp, but I'd also suggest a very good parmesan.

We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
