Squash is hard, so use caution when cutting it. Use a large, sharp knife and cut off stems, then slice in half lengthwise. Use a spoon to scoop out the seeds.
Filled ravioli made from wonton skins can be frozen. Cook the number you would like to serve, then freeze the rest. Arrange filled ravioli in a single layer on a tray and freeze 1 to 2 hours or until they are firm. Transfer to a freezer storage bag, label and freeze. No need to thaw when cooking, just increase the cooking time about 1 minute.
A small scoop, sometimes used for cookie dough and holding about 1 tablespoon, makes it quick and easy to spoon the squash mixture into the center of the wonton skin.
