Preheat oven to 350°

Cook pasta according to package directions.  Be sure not to overcook!  Drain and set aside.

After the tofu has been pressed, crumble and add to a food processor.  Add nutritional yeast, fresh sage, oregano, dry sage, vegan parmesan, lemon juice, salt, and pepper.

Pulse until ingredients begin to combine into a ball stage.  Remove from the food processor and add to a medium-size bowl.  Fold in pumpkin puree, maple syrup, and baking spice mix—taste for salt.  Mix well. 

Give the pasta noodles a good rinse (they might be a little sticky).  Shake off excess water.  In a 9″x12″ glass baking dish, spread 1 cup of béchamel sauce on the dish’s bottom.

Carefully remove a conch shell and place it in the palm of your hand.  Gently squeeze each pasta shell until it opens.  Using about 2 Tbsps of filling, fill each shell until your pan is full.

Drizzle with remaining 1 cup béchamel sauce, being sure to coat all of the noodles well.  If using, top with additional parmesan cheese.

Bake for 20-25 minutes. Turn oven up to broil and carefully watch until the parmesan cheese has melted and lightly browned, about 2 minutes. (Be careful not to walk away from a broiler as it can burn very quickly).

Let cool and plate.  Drizzle shells with remaining béchamel sauce from pan. 

Taste for salt and pepper.
