Shrimp and asparagus in white sauce

We both love shrimp and asparagus is in the stores now. This calls for a shrimp and asparagus dish.
I would like to thank Deborah's blog Taste and Tell (April 26 2007) for this one and we will be making it again as it was fairly easy. We may try adding some onion and red pepper flakes next time. A nice salad and a crusty bread to get that last bit of sauce. Yum Yum
