  1. Set oven to 350 degrees F.

  6. Stir in onion mixture and spinach; mix well to combine.

  9. Arrange shells over sauce (at this point you may cover and refrigerate for up to 24 hours, or continue with the recipe as follows).
  10. Top with the remaining sauce, use a spoon to spread the sauce over the shells (the sauce does not have to cover the shells completely).

  13. Uncover and top with mozzeralla cheese (any amount desired).
