I haven't posted here for so long, and I really need to return to
the fold.  Here is a divine LC appetizer, which I have had at a
restaurant.  (I wonder how it might be in portobello mushrooms as
an entree.  Overkill?)  It is essentially this:

Mix surimi/crab with spicy mayo (like that used in some sushi).
Use this to fill mushroom caps (not portobellos, bite-sized ones).
Sprinkle tops with a bit of cheese--type unknown.  Might be
parmesan.  It is sharp.
Bake or broil (not sure which) until the mushrooms are cooked, the
filling is hot, and the cheese is browned.

These are soooo good.  I think I'll post this elsewhere to share
the delight of it all.
