Preheat oven to 400 degrees.

In a food processor, blend tofu until smooth.

Add lemon juice, garlic powder, salt, nutritional yeast flakes, turmeric powder and soy parmesan cheese (save a little to sprinkle on top of pie).

In a skillet sauté onion in olive oil until translucent.

Stir in sausage crumbles and continue cooking on low about 3 minutes.

Stir in chopped spinach. Stir sausage, spinach and onion mixture into tofu mixture.
