My family decided to make a Butternut Squash Lasagna for Thanksgiving as our vegetarian main dish and I was not completely satisfied with any of the recipes I saw on Zaar. Some of them were too complicated or too high in fat and made with heavy cream or too low calorie and bland. So I took bits and pieces from each recipe and came up with this one. I originally made it in a 9x9 inch pan so I'm not completely certain about the following measurements. One serving is 1/4 of a 9x9 inch pan and has about 300 calories.
