Someone at work gave me this recipe and said it was from Weight Watchers or something. She had made the low-cal version for our Thanksgiving meal at work and it was great. I made a non-low-cal version tonight and it's also great. But if you don't like pumpkin, then don't bother.
One can of pumpkin filling (15 oz.)
One tub of Cool Whip (12 oz.)
One box of Vanilla Pudding mix (small box that makes "4 servings")
Pumpkin spice to taste
Mix all ingredients together and whip them thoroughly. Allow to set in refrigerator for a couple of hours, if you can wait that long.
You can get the "lite" or "sugar-free" versions of the Cool Whip and pudding if you want.
Slather the resulting stuff in a graham cracker pie crust and serve like pie, or use as a dip with graham crackers, or just eat it out of a bowl like pudding.
