Okay, so I'm a huge mushroom fan. Yum! I add 'em to just about everything I cook. Today at the grocery store, I bought some Portobello mushroom caps. They're always so good in restaurants. But, I've never tried to cook them before and would love not to screw them up

.
I assume I should throw them on the grill, but am wondering about seasoning and marinades and whatnot.
Anybody have any suggestions?
Thanks in advance!
cheers!
