Fall has arrived and with that all you favorite pumpkin desserts and dishes. This vegan pumpkin Alfredo pasta from Jessica's Gluten Dairy Free Kitchen is the perfect way to celebrate the season. Penne pasta is tossed in a sauce flavored with onion, pepper, pumpkin and nutmeg. You can use fresh or canned pumpkin for this recipe. If you decide to make your own pumpkin puree, use small sugar pumpkins because they have the best flavor and texture for eating. Serve your harvest pasta with a side of autumn greens and garlic bread.
