Hey C.,
Check the regular online recipe sources, recipe.com, allfood.com, etc. You are going to find that there is practically no detectable taste difference between pies made with fresh pumpkin and pies make with canned pumpkin. There is not a "mix" for pumpkin pie. It is basically crust, pmpkin puree (either fresh or canned), sweetenend condensed milk, and various spices.
One caveat, do not get the "pumpkin pie filling" can- the spice flavors tend to be artificial tasting. Just get plain pureed pumpkin in a can.
You are going to have a great first Thanksgiving together!
