Preparation
Cut squash in half lengthwise and remove seeds. Prick 
rind with a fork. Place cut side down in a baking dish and add 1/4 inch 
water. Microwave squash on high 10 minutes, checking for doneness. (To 
bake: Preheat oven to 350°F. Place cut side down on a baking sheet. Bake
 until soft, about 1 hour.) Remove and cool. Scoop out flesh and place 
in a medium-sized bowl. Mix with salt, pepper, and nutmeg. Heat oil in a
 medium-sized pot over medium heat and sauté onions until light brown. 
Remove from heat and cool. Season with salt. In a separate bowl, mix 
cheeses. Make crust. While second side of each crust is grilling, spread
 1/8 cheese mixture over cooked side of each crust and top with onions. 
Top with dollops of squash; sprinkle with parsley. Rotate 3 to 4 minutes
 until bottom is golden brown.
