OK - I hate to be this brief, but I saw this in my blogroll this morning and had to post this link IMMEDIATELY because if I wasn't at work, I would so be drooling right now.
Pasta with Slow Cooked Portobello Mushrooms from Mark Bittman. I've recently started worshiping at the altar of Bittman and this recipe is one of the reasons why I'm an acolyte. I cannot WAIT to try this!
Drool moment over! And out.
