In a large bowl, combine the shredded butternut squash, flour, eggs, minced sage, ¼ teaspoon salt and 1/8 teaspoon pepper to the bowl, stirring until the mixture is combined. Line a plate with paper towels.
Liberally coat the bottom of a large sauté pan with vegetable oil and place it over medium-high heat. Once the oil is hot, scoop 3-tablespoon mounds of the mixture into the pan, pressing them lightly into rounds and spacing them at least 2 inches apart. Cook the fritters for 2 to 3 minutes, then flip them once and cook an additional 2 minutes until golden brown and cooked throughout.
Transfer the fritters to the paper towel-lined plate and immediately sprinkle them with salt. Repeat the scooping and cooking process with the remaining mixture.
Serve immediately with a generous dollop of (vegan) sour cream & some freshly snipped chives.
