For the shaved Fennel Salad:
Salt and pepper to taste
Make sure your mushrooms are clean of dirt. You can do this by Gently wiping them with a paper towel/kitchen towel. Don't submerge them in water! Mushrooms are like a sponge and absorb water, you won't get a good roast on them if they are full of water!! The mushrooms need to be cut into the same size... Sometimes it's easier to pull mushrooms instead of cutting them. How ever you can or what ever is easiest for the "cook" portion the mushrooms and place on a sheet tray. You can use what ever mushrooms are available to you. I make this with only button mushrooms and it is delicious!
Also, as a cook, it is a good idea to get in the habit of cooking with your nose! You will be able to smell the mushrooms when they are roasted and ready, once ready, pull out of oven and let "rest" until you can handle them.
For Fennel Salad:
Ps- you can eat this dish room temperature or you can use the mushrooms while there still warm, up to you. I like room temperature.
