For the strawberry sauce:
In blender, blend the 2 cups of chopped strawberries with one cup of water. Pour in medium bowl and add sugar. Cook at medium heat, stirring from time to time, until mix changes color. In a small bowl, mix one tablespoon of cold water with corn starch. Stir in cornstarch mixture with the strawberry sauce, and continue cooking for a minute or two, until it thickens. Remove from the heat and let cool.
