1Prepare squash by cutting off rind and seeding it. Cut into small chunks.
2Cook enough cushaw to equal 2 cups. This can be done by putting a small amount of water in a pan and slowly cooking it so it won't stick. Another way is to put cushaw in a microwave safe bowl, cover and microwave until soft.
3Put cooked cushaw in mixing bowl.
4Add remaining ingredients and mix until blended well.
5Pour into pie shell and bake at 350 degrees until done, about 45 minutes or until center doesn't jiggle.
