I don't have a gnocchi recipe, but I thought I'd share these two recipes we love:
Skinnytaste.com has a recipe for Butternut Squash & Spinach Lasagna Rolls, and also a Spaghetti with Creamy Butternut Leek Parmesan Sauce. My iPad is acting up today and won't let me copy and paste the links, I'm sorry!
Butternut squash puree freezes extremely well so when I have extra from a recipe or find a great deal on squash, I cook it, puree it in my Vitamix and then freeze it. I try to freeze it in the quantity I use for recipes.
