My sister just told me that she's been making her burgers by using very
lean (90/10) beef, or ground turkey and adding a lot of finely chopped
button mushrooms, season and grill as you would normally. She got this
tip from some Alton Brown show which I've not seen. Says the burgers
are fantastic this way, and they add a lot of moisture to the very lean
beef, allowing for cutting back on fat, and also contribute a nice
texture to the burger. Anyone else use 'shrooms this way? I'm going
to try it soon and see how I like it.

Happy Tuesday evening,
Sandy
