Preheat the oven to 400°F (200°C) and lightly grease a baking sheet. Separate the biscuits and roll each one into a long rope, about 12 inches in length. Tie each rope into a loose knot, tucking the ends underneath to keep the shape neat. Arrange the knots on the prepared baking sheet, leaving about 2 inches of space between each.
Bake for 8 to 10 minutes, or until the knots are puffed and evenly golden. While they bake, combine the canola oil, grated Parmesan, garlic powder, oregano, and parsley in a large bowl, stirring until well blended.
Remove the knots from the oven while still warm and brush them generously with the Parmesan mixture, coating all sides. Serve immediately. Yield: 10 knots.
