Sarah,
I'd even eat raw mushrooms chopped and put some lemon juice on it if needed so they remain fresh looking. Great tips and the base is lettuce. ASM has fantastic ideas always... and i have to try the nopalitos yet
I got a good salt and spice mix from someone, it is pretty fine, see nahrin, aka nahrin.ch for gewuerze-mehrsalz,
http://www.nahrin.ch/htm/produkte/Gewuerze at the bottom, mmm, tasty. A little olive oil, lemon juice and all's good to go.
