One of my friends is an EXCELLENT cook, so whenever we jam at his place he makes dinner.
Last time was Lasagna, with noodles made from scratch, four kinds of cheese, extra sauce on top and a dozen Italian names for all that which I forget.
Pizza nights, well we've had a few before getting down to the jam space... notably though:
One time he made an experimental REUBEN pizza and it was DAMNED FANTATASTIQUE!
sock(et) it to me! 111 more times.
