WOW! This is only my second try at a recipe from RZ, and I'm 2 for 2! These were SO good, we ate them plain, didn't put them on the buns. I followed Debra8940's suggestion and added the sauce onto the gills (never knew what that accordian was called!) and it was fabulous. Next time I'll have brown rice ready and put the extra sauce on it! Excellent.
