Combine the chocolate chips and walnuts in a food processor and pulse on and off until finely chopped.
Scatter the chocolate chip-walnut mixture evenly over the bottom of the pie crust and set aside.
Combine half of the tofu, half the cream cheese, and half of the sugar in the container of a food processor and process until smoothly pureed. Pour into the pie crust and smooth down with a cake spatula.
Combine the pumpkin or squash pulp in the food processor with the remaining tofu, cream cheese, and sugar, along with the cinnamon and pumpkin pie spice. Process until smoothly pureed.
Pour the pumpkin mixture into the pie crust over the tofu layer. Smooth down with a cake spatula.
Bake for 40 to 45 minutes, or until the mixture is set and the crust is golden.
Let the pie cool to room temperature. Cut into 6 or 8 wedges to serve.
