I *finally* made your stuffed mushrooms last night. Wow! I did make a few substitutions, but they were excellent the way I made them.
Instead of parmesan, I had to use romano, because that's all I had. I needed more filling (I didn't multiply your recipe enough for as many 'shrooms as I made) so I added cream cheese and bacon. I also didn't have saltines so I used Ritz crackers. AND since I was low on EVOO, I used some butter as well.
Still, it's an excellent recipe and I thank you!

P.S. I forgot to mention that my neighbors enjoyed them, too, and gobbled them up!
