Costco Pumpkin Pie is Vegan as well as being gluten-free, and non-GMO.
If you have a gluten allergy and you're vegan then eating Costco Pumpkin Pie is a good option.
Most other pumpkin pies are vegan and contain no animal ingredients.
As long as the pie contains no animal ingredients which Costco Pumpkin Pie and other Pumpkin Pies do not contain then Vegans can eat it.
I love Costco Pumpkin Pie and it's where I buy all my Pies including Pumpkin Pie from for Thanksgiving and Christmas or just anytime I want Pumpkin Pies.
Homemade Pumpkin Pie is also vegan and you can make the Pumpkin Pie with your own ingredients so you know what is going in it.
