Add in the crushed tomatoes, pumpkin puree, sage, cinnamon, oregano, garlic powder, salt, pepper and sugar. Stir and then add in 1 cup broth and stir again. Add more broth if the sauce is too thick for your liking.
Bring the sauce to a light simmer and then cover and cook on medium/low for 15 minutes.
Serve with spaghetti or meatballs. You can store in an airtight container in the fridge for up to 3 days or in the freezer for up to 3 months. Enjoy!:)
