In a medium bowl with a mixer beat butter with powdered sugar until smooth.
Add flour, salt, pumpkin pie spice, nuts, and vanilla, and orange food coloring, mix until incorporated.
Roll into balls.
I use a tablespoon size scoop.
Place a pumpkin seed (pepita) into the top of each cookie
Bake at 325 for 15 minutes.
Alternatively you can roll them into powdered sugar if you want to keep the orange color pumpkin a secret!
