Toast pumpkin seeds in a dry skillet over medium heat. Keep them moving in the pan with a wooden spoon until they begin to puff up and give off a nutty aroma. Remove from heat before burning.
Place pumpkin seeds, garlic, parsley, and sea salt in the in the bowl of a food processor fixed with the s-blade. Drizzle olive oil little by little through the opening at the top of the food processor until mixture is well-blended yet slightly coarse.
