ooh, these are a favorite of mine!

for spices- i liek to sprinkle mushroom with seasalt
spices i add to toss, after cooking- crushed red pepper, parmesan, basil......

for toppings- you can add olives, onions and peppers, artichoke hearts, pepperoni, sausage, fresh tomatoes, etc....

i like them best with extra cheese and extra garlic
