The Martha Stewart Recipe looked good, but almost too simple. This other recipe included mushrooms, which I wanted to use up, but I liked the idea of Gruyere more than creme fraiche (and didn't want to pre-cook the veggies).So, I ultimately used packaged puff pastry, rolled it out on a baking sheet, put a super (super!) thin layer of Dijon mustard on it, sprinkled it with shredded gruyere, a thinly sliced green onion, a little bit of minced fresh thyme, parsley and rosemary, S&P, and then laid out raw asparagus and mushrooms in an artful way. Brushed the top with olive oil and more S&P and stuck it in a 400 degree oven for about 20 minutes. The only thing I would do differently next time is grease the baking sheet a wee bit.
Tasty and definitely cool looking!!
