Here's something simple and easy, yet fun, providing
unusual seafood is your idea of fun.
You need a medium to large squid tube (the head
part, not the tentacles), a bunch of white mushrooms,
butter, and bamboo skewers. When preparing kebabs for a bento box, keep in mind the
size of the compartment they'll be in. The skewers may
be able to go over partitions, otherwise you might have
to cut them short. I have no problem with 6" skewers.
Cut the squid tube into inch-square pieces. Cut the
mushrooms in halves. Skewer them, alternating between
squid and mushroom, making sure that they touch and
the end piece is squid. Brush 'em all over with
melted butter. Then place them on a heated grill. (I
use a George Foreman.) Grill for a minute, then turn
and grill some more, making sure all sides get equal
attention. Brush with the runoff butter and juice to
keep it moist. It's done when the piece of squid on
the end turns opaque white down to the skewer. Don't
cook it longer or it'll get tough!
I haven't made this on a regular grill, but if I
were to the first thing I'd do after buttering it is
to wrap it in tinfoil to evenly distribute the heat
and keep it from drying out. If anyone tries this, please
let me know how it worked. I wouldn't mind suggestions
for spices and things to add to the skewers, either.
