Preheat oven to 400 degrees and lightly grease a rimmed baking sheet.
Cut each biscuit in half and roll each piece into a skinny rope. Tie each rope into a knot.
Place knots on prepared pan.
In a small bowl, stir together melted butter, garlic salt, oregano, parsley, and red pepper flakes. Brush mixture on each knot.
Sprinkle the Parmesan cheese on the knots.
Bake for 10 to 12 minutes. Remove from oven and brush with more butter.
Serve with pizza sauce.
Notes
These knots taste best right out of the oven, but leftovers can be stored at room temperature in a zip-lock bag. You can rewarm them in a 300 degree oven or the microwave.
