Roasted Asparagus with Romesco Sauce

There are few vegetables that are not improved with roasting, but it really works wonders with asparagus. Get some nice not-too-skinny stems and keep an eye on them in the oven so they char but still have a bit of bite. This recipe is very adaptable: I really like it with shavings of nutty Manchego cheese, or with torn pieces of Serrano or Ibérico ham draped over the top.
