Boil a large pot of salted water. When water is at a rolling boil, cook pasta according to al dente package directions.
Combine kale, spinach, basil, and olive oil in a food processor. Blend on high for 2 minutes, until the greens are mostly broken down.
Add sunflower seeds, garlic parmesan, and a pinch of sea salt to the food processor. Blend on high, until all ingredients are combined and the sauce is smooth.
If needed, add a little more olive oil and blend more to create a smoother sauce. Serve over drained pasta.
