Trim the stems off of the shiitakes and wipe any dirt particles from them. Cut into 1/8-1/4"thick slices.
Heat the neutral oil on medium in saucepan, and sauté the mushrooms, just a couple minutes, tossing until lightly browned, remove from heat.
Mix all the marinade ingredients, including the dry spices, and whisk together.
Toss the mushrooms with the marinade and chill until ready to make the slaw.
Make the slaw
Slice the cabbage thinly. You can use any combination of green/purple cabbage.
Slice the green onions thinly then chop them similarly to the way you chop the fresh herbs.
Mix all the slaw ingredients together in serving bowl, add the marinated shiitakes and all of the marinade and toss all together.
Squeeze the 1/2 lemon over the slaw and sprinkle with the salt, and toss again. Taste and adjust if needed. Serve or cover and chill till serving.
Notes
Coconut Sugar: ok to use white sugar but light or dark brown sugar is too moist. Read the post about reasons to use this less common sugar.
Aleppo chili flakes: ok to use red chili flakes. Aleppo flakes are a bit more fruity and less hot. Also, double the amount if you like a good amount of heat.
Ground mushroom powder: I use dried shiitake. They are located with jarred garlic in the produce department at my grocery store. You can buy online as well. I filled the coffee grinder with about 4-5 to get 4+ tsps worth of powder. This ingredient is optional. It adds layers of flavor but is not crucial.
