I found this recipe on 
this blog.    It is so good (if you like pumpkin pie) and is a nice alternative to pumpkin pie.  The other thing I love about it is that it is a gorgeous presentation without being hard!  It is really easy (just remember you have to make it the night before because it has to sit in the refrigerator over night).  I took it to a Halloween party and it got rave reviews.  I think it would also work perfectly for Thanksgiving dessert!
Pumpkin Gingerbread Trifle
Here's the Recipe:
Ingredients:
2 (14-ounce) packages Gingerbread Mix 
1 (5.1-ounce) box Cook-and-Serve Vanilla Pudding Mix 
1 (30-ounce) can Pumpkin Pie Filling 
1/2 cup packed Brown Sugar 
1/3 teaspoon Ground Cardamom or Cinnamon 
1 (12-ounce) container Frozen Whipped Topping 
(Shelf-Stable Cream can be substituted here.
Just refrigerate, whip, and add a little powdered sugar and vanilla.)
1/2 cup Gingersnaps, Optional
Instructions:
Bake the gingerbread according to the package directions; 
Cool completely. 
Meanwhile, prepare the pudding and set aside to cool. 
Stir the pumpkin pie filling, sugar, and cinnamon
into the pudding. 
Crumble 1 batch of gingerbread into the bottom of a large, 
pretty bowl. 
Pour 1/2 of the pudding mixture over the gingerbread, 
Then add a layer of whipped topping. 
Repeat with the remaining gingerbread, pudding, 
and whipped topping. 
Sprinkle of the top with crushed gingersnaps, if desired (I just sprinkle cinnamon on top). 
Refrigerate overnight.
