I got this recipe from LiveVegan.org
(If you're brown, you may wanna sub the pumpkin for sweet potato :-) but its good both ways.)
1 can pumpkin puree
1 ripe avocado
3 Tbsp. grade B maple syrup or agave nectar
2 tsp. pumpkin pie spice
1. In a blender or food processor, add all ingredients and mix until smooth.
2. Chill and then serve!
